Do you ever split because of intimacy?

Like if your FP(s) is/are too intimate while you're splitting then it makes it worse, but if you're idealising them and they're not intimate enough then you split?

It's like a never ending battle of wanting too much or not wanting it at all. Either I'm not getting enough love and feel like they hate me / feeling like I'm asking too much or feeling like I'm smothered / being used and wanting nothing to do with them.

Nothing ever seems to be just normal, and I know it's all mental because all my relationships seem to have enough affection and warmth, but I just can't seem to stop. I'm just tired of wanting constant reassurance and then flipping on them if I don't receive it eventhough I know in the back of my mind that they care for me. And then constantly apologizing when I snap out of it.
