<human>: My (25) boyfriend of a year and a half has started to "crush" on a co worker (20) of his. She's as he describes her "fit and pretty". She is pretty. 

We haven't been too okay lately. I lost my car at the end of the summer. And we did a lot of bonding just driving. I haven't been feeling okay lately. Losing my car because I lost my good job. I'm not so fit....at all. I mean I'm not horrendous but I'm not fit. So anyways I guess I just haven't felt so pretty lately. He used to make me feel so fucking special. But him leaving me for her is all I think about. Or going down to there job and breaking her fucking skull.....my life feels like a mess. 

The same day I found out about his crush I lost my mediocre 25 hour a week can barely afford food let alone rent and a car job. I guess we are kinda on a break....I don't really know anymore. I was so sure of him, of us. He really made himself out to be better than the rest. 

And he is. Because he does love me. And I can see he is hurt and confused. But so am I. He told me last night he wishes he could have us both. And that sucks. Why am I nOt enough? I understand I've been pretty miserable. Honeslty to the point of questioning existence. 

Is it really not his job to make me happy? Is it really so unfair of me to look to him to turn my day arpund? I talk to him all the time I tell him exactly what would make me feel happy and he said he can't just turn a switch and tell me sweet things. But is it really that hard if you do love them?

He left for work earlier and before he left he said he missed her. It just hurts.
