<human>: Can you summarize the given text in a few sentences?

I just need to vent because I'm thinking about breaking up with my girlfriend of 3 years because I don't think I'm meeting her needs. We know we're in love, and we have a very good relationship, but tonight she admitted that her confidence was at an all time low, and it really tore me apart. I asked her what I could do to help and she said I couldn't. When I asked her if my compliments did anything, she says she didn't believe them. Which really messed me up because I genuinely mean every word I say to her. She really is the sunshine in my life, and I believe her when she tells me she loves me to death and stuff. However, I don't know if I can help her confidence, and we are currently in a LDR for at least another year. I am thinking of breaking it off with her simply because I don't know if I can satisfy her needs. I would honestly rather see her happy and confident with someone else than depressed in an LDR with me. I really don't know what to do about this. Thanks for listening r/offmychest.
