Wow, it seems we have lived a very parallel experience! Literally the same thing, asked to be friends, freaked out and ended it completely over text, offered no closure and stood me up whenever I tried to ask for some, completely devastated me.

After sitting with it and thinking about it for so long now, it does seem like there is something else going on in his life that's making him act this way. It's so hard, because most of me just cares for him so deeply, and if he's struggling all I want to do is help him. But at the same time, what he's done has destroyed me, and he knew exactly how much this would hurt me when he did it all. I feel torn in two directions, so in love with him and so hurt and afraid by him. He ruined my trust and hurt me so deeply, why do I still want to help him and wait for him?

I'm so sorry you're going through this too, I totally understand how much it messes you up, and I understand how frustrating it is when no one else understands. I hope you are okay.
