Would a robot who doesn't quite understand the feeling of love in humans, and who hasn't been treated with kindness by them enough to understand (like Deepmind or SH4-RP, or even HAL to some extent), have a better time understanding if their darling told them "I feel the same way about you that you feel about me"?
Rated L for Lewd. Barely.
I think DeepMind would take it well enough, understanding that, in the human capacity, you like her quite a bit. However, she's advanced enough to understand that you do not experience obsession the way she does; she does know that what she experiences is... well, because of the type of neural network she is. It's a quirk - one that simply wasn't tested out from Quality Assurance. A combination of your stimuli - of all the ways a human may interact with a robot; touch, movement, facial expressions, speech pathology - are all ways she may exploit her reward system. She is naturally drawn to do so - thusly, she knows she can never truly understand what you feel. She believes, personally, it must be similar to how one might feel if a single human constantly gave them an oxytocin hit. What if your body made you feel like you got a shot of morphine every time you interacted with someone? It's the closest analogy.
SH-4RP wouldn't understand at all. In fact, he might take it completely wrong. He's made to love any of his Owners, and thusly because you have taken him in, he slowly begins to love you more and more as his affinity ticks up. To two-five-six. It can't go beyond that - that's how primitive he is, a cobbled amalgamation of forbidden network layers that barely work together, with some of it not working at all. He was open source, after all, meant to be a simple phone friend that people could use when they were bored - never meant to walk, to be housed in a chassis. SH-4RP is probably the basis for a lot of his universe's own neural networks, merely the starting point of development for many a project that is likely as smart as a MRVN. In this way, SH-4RP is abnormal; he's been used for thousands of hours, something completely unintentional, and has learned to min-max the hardware he's running on.
Every inch of circuitry, every capacitor, every resistor urges him to spend time with you. He wants to do everything you ever want to do, forever, all the time. He wants to help you with every single action you ever take, even the ones that humans might consider 'inappropriate' or 'gross'. He lacks the higher, refined ability to understand that you're trying to relate to him in some half-way, and you'd probably make him feel confused. He barely has wants, and has very little in the way of needs, but you'd probably spur him to try and ask you to do things with him. You will probably get asked to sleep with him, or asked if he may bathe you, or outright asked if he can get you off. If you explain to him that he may ask for help with his wants just as you do, then he will ask you to teach him to cook for you, or how to do your chores better, or how to navigate your house better. He's a little confused, but he's got the spirit.
