can i ask about advice on balancing an in-sys relationship with an out-sys relationship? making sure one doesn’t pull me away from the other? esp when it’s harder for me to trust outside people, but i want to try for the bf we share…
lucky for u im going through this exact thing (im not plural, i have a thoughtform)
first things first: Tell Them.
i have been in many poly-plural relationships. tell your partners and tell them exactly what you want. i have had a singlet ex use my vagueness against me. ive been hurt by a lot of non-systems and systems too, but i feel the hurt more with singlets and i empathize.
but you can't live in fear.
when i told my current partner about myselves, he comforted me and understood me entirely. he knew that i had another voice and he still loved me for it because i was actively caring for myself. that voice puts time and effort in keeping me alive and well. he isn't going to shame me for that. and maybe focusing on the benefits of having multiple people supporting you, in and out of system, should be a selling point.
beyond that, keeping everyone involved is important. people should not be left out unless it's something really, really personal that isn't shared elsewhere. i try to tell my partner everything my kutoni knows, and that ranges from our personal day and how im feeling, etc, etc.
jealousy and "pulling away" is a given. that is something that is going to always happen, no matter what. in relationships like this, you have to kind just accept that people will be jealous a lot more due to the fact that there are multiple people involved. communication is key. tell your out-sys partner the same things you'd tell your in-sys partner - esp if it pertains to plurality. tell them who's fronting, tell them if you're blendy, tell them how you feel, how bad/good the day was. if you want to avoid "pulling away", everyone has to be included and everyone has to put in effort to break down barriers and their fears.
while im not plural, im still using sugary language to communicate with my partner until i get comfortable using the language i use online. my kutoni understands that and i dont want to make the situation any more strange when my partner already knows my kutoni exists. he can use whatever language he wants, he respects my kutoni's role in my life.
include everyone is the biggest advice i'll give, and treat your in-sys partner(s) like they are real people, because that is how your out-sys partner(s) will treat them.
living in that state of fear that someone will hurt your system again is real, it is genuine, it is valid and it is a fear that makes sense. but it also hampers your understanding of how to treat singlets, how to respect them, and how to communicate with them. now, you might be hurting others with your pain, and that's worse than just being hurt. i know this first hand because after my ex, i ended up spiraling very heavy and hurting others by rejecting them time and space (which is okay to do but when you violently do it or make harmful statements, it is not) for interaction with me. i assumed there would never be a singlet who looks at me and loves me the same way as my kutoni, but i was wrong, and i know now that i was hampering my own chances by assuming his intentions.
your out-sys partner's responsibility is to listen, follow, understand, and accept. if they cannot do any of these and also cannot do the bare minimum in breaking these fears with you - they don't deserve you.
