I finally told my boyfriend I love him and he responded that he doesn't know if he loves me and he's not sure if he's even capable of love. And, which hurt me the most, at some point a year ago he felt the need to tell me that he loved me because we had two great days but then we had two days that weren't so great and he has never felt that need again. 

It's like his love depends on my behavior and I'm never going to be good enough to be loved.

I feel like I'm a lost cause. Is being loved too much to ask?
