Can confirm as a disabled person, and to add further context for people who still don't see that it would be a prevalent issue...
Not only will people, looking for someone to -consciously- target, zero in on you and put up a really good act until they think you're stuck... But perfectly "normal" and "oh they/he/she would nEvEr do that!!" Kinds of people rationalize their way straight into abusive behaviours, consistently, when they get the hint from everyone around them that they will be supported, you will be seen as the burden, and you don't have enough financial independence to leave.
These people may have ever leaned that way without being put in a relationship with a power dynamic they can take advantage of, without it being handed to them, but once they're there, and can benefit from doing it with no repercussion and with the normal human ability to rationalize away anything for convenience... They sink into it like they're under some kind of spell.
And -to put it frankly- that's most people. In my going on 36 years of experience, that is MOST 'decent' seeming people.
In my personal experience it happens every time. EVERY time. And if you stick with me I can explain how your own "judgement" doesn't matter, and how there isn't any control you can wrestle out of the situation, no matter what you do. The moment you are disabled you are either vanishingly lucky, or fucked.
Because in a normal relationship, when the other person isn't happy or is even just dissatisfied, they can leave, you could leave. But when you can't afford to live on your own, and can't afford to keep moving house, not only are marriage and romantic relationships dangerous, but ANYONE -in your home or close social group- can start being abusive to you and if nobody understands how what they are doing is harming you --because of societal biases, personal biases, or because you are disabled in ways that make 'normal' things have dire fucking consequences to you... If no one wants to advocate for you or "take your side"-- you're just stuck with it [unless you want to start breaking out psychological warfare tactics, or you think the police will actually DO something if you get them involved that won't just come back on you later.]
And it's much WORSE if you actually are considered to be "in a relationship" and fully lose your income. Here in Canada, it doesn't even require marriage, it often only requires living with someone of the opposite sex for long enough, or having previously had a relationship/fucking long enough to have a child. Any grounds the government can use to try to CLAIM you are in a "marriage like situation" they take, and harass you with constantly, putting the burden of proof on YOU.
And in my substantial experience, like with most abusive relationships, no one believes you or takes it seriously. ESPECIALLY if what they are doing is only harmful to you because of your disability, it's too abstract for most people to understand, on top of the usual victim blaming nonsense.
So all your friends take their side, sometimes even your own family, like with most abusive relationships, and the cops won't do anything, as per usual...
but unlike anyone else in an abusive relationship cycle, you don't GET to stop. You don't GET to take time to yourself to stop, to think, to recover, to live as a single adult. You HAVE to have roommates or a partner, or you can't afford a place to live, so you CAN'T take time to pick and chose, or learn to better "identify" "safe" people. You simply rush into whatever next rental situation or partner will take you because otherwise you're disabled and also out on the street or entirely penniless... Which for many of us is a death sentence, especially now.
So the next people you encounter to rebuild your social circle or your housing situation all see walking into it that you are vulnerable and have no recourse. They HAVE to know as a product of you LIVING with them or being dependent on them for rent, etc... There is no making connections to see how they go over time without them immediately knowing you are disabled and financially dependent, and being able to put on whatever act they need to, knowing they only have to maintain it short term to trap you.
To say that attracts potential abusers is a GROSS UNDERSTATEMENT. Because even your average 'actually decent' person isn't actually looking to spread themselves even thinner to have a disabled partner, friend or roommate, when they could just as easily get along with someone who can meet them half way all the time. Your social relationships suffer from the same problem as employment, or any other vulnerability in meeting people. Why hire you out of 30 similar candidates that are a lot like you but less work for more reward? But do you know who's EAGER to make fast friends with you when you are disabled and dependent? People who see that they can get something out of that relationship. People who see you as vulnerable enough to let them in. People who know there's something wrong with their behaviour that has kept them from maintaining other relationships; people who have driven away anyone, who had more of a choice, and seek out relationships with power dynamics out of insecurity; the people who will naturally gravitate to the one person who CAN'T say "no"... Your next abuser.
Because everyone else who isn't abusive isn't rushing headlong into a relationship of some kind with you on the timeline you need to have a place to live lined up! They get to take their time testign the waters of new social connections and deciding who they actually get along with as they get to know people over time... But abusers and people with abusive habits or beliefs ARE rushing to get the next person in their lives hooked right where they need them. THEIR main priority, conscious of it or not, above any other trait you have, is feeling like their power over you is assured [sometimes internally framed as finding someone who won't "make them feel bad about themselves :("]. They aren't picky.
And it's that simple! And the abusive ones come surrounded with a social group that habitually enables them, or they wouldn't be there! And you just lost all your previous connections and relationships and have an open roster for new ones! The next circle of friends who will all turn on you when things go south.
On repeat until you are dead, trapped permanently in an abusive relationship, or by some miracle find a way to afford rent by yourself.
And you up that risk factor to positively life and death the moment you concede, not just to marriage, but to be in any committed relationship with anyone. [The only potential advantage gay or poly people have in society is that often the government won't hound them about being in a relationship under these circumstances because if they start hounding just any roommates about all fucking each other they suddenly back themselves into HAVING to approve universal basic income... be gay, be poly, and commit fraud ;)]
That's WHY we need universal basic income. ESPECIALLY for the disabled. A minimum income that will let them rent alone REGARDLESS of relationships status.
Because the system where that isn't the case, is just government sanctioned/forced abuse or even enslavement.
