My boyfriend has told me at some point that he felt like he was getting a lot from me and was giving very little. However, I never felt that way. If he broke up with me over that, I would be devastated. Your partner may get things out of the relationship that you don't realise. At any rate, as I've said in another thread, it's their decision here. I feel like breaking up with someone because you think they're not getting enough from it is a bit condescending, like they don't know better and you have to step in and let them know or something.
