I'm looking for some advice or support.

I met a dude on here, really vibed with him. We talked a lot for a few months and he definitely became my FP. Everything about him and the situation kinda made me feel crazed. Constantly jumping to the worst conclusions, being mean to him for no reason, then profusely apologizing and worrying he'd abandon me.

No surprise here but it all got too much for him and he just blocked me on everything about a month ago. I noticed yesterday that he unblocked me and I quickly blocked him just to try to keep that distance. Idk if keeping him blocked is the best idea or if I should try to explain things more. Half of me really wants my friend back and would do absolutely anything, while the other half knows it would be so much easier to not go back to feeling like that and to just stay no contact with him. Any advice? Anyone else have any relatable experiences?
