my girlfriend of 5 years broke up a few weeks ago, with her having cheated on me emotionally with my best friend, ruining entire social circles for me after a meltdown i had.

I still care about her, but after my mental unstability she has blocked me, and im respecting that as best i can. but, she was my routine, every week we hung out and such. the transition has sucked, to say the least, i had become suicidal on multiple occasions.

i just wish i could move on like she has (also autism+adhd) but i dont know how to navigate going forward. people say be there for yourself, but i was there for her for so long... its hard to know who i am?

has anyone else gone through a similar situation?
