I'm sleeping with my ex-gf of 3 years ago. Since then I've been in about 3-4 relationships. She's in a relationship while I'm not, she reached out to me and we've been seeing each other discreetly for 2 months. I feel as If i'm beginning to be more invested, and asking more from her when I know I can't get anything more. We meet / fuck twice a week, but we seldom text anymore, and the sex is dwindling and when I felt her becoming more distant, I told her we should end it as I could feel it was coming to an end.

I get the I love you but I cannot be with you blah blah and says she did X, she felt Y but didn't want to show it. But it's all bullshit without the action to back it up. I feel a bit heartbroken knowing it's ended and nothing could have happened with it, because she had a boyfriend. But knowing a woman could just light switch like that. I'm not sure if it's onitis, infatuation or because she was my first love but I'm feeling pretty god damn broken right now. I told myself in the beginning to be outcome independent and enjoy the sex, but when this happens so suddenly it sucks.
