I've been seriously thinking of breaking up with my girlfriend lately. I love her and I want her to be happy, but her rancorous personality makes me feel a bit more miserable every day. It's true that we've had many fights in the last few weeks, but while I try to forgive and forget, she tends to bring out previous arguments in each new one. Whenever we end up speaking of breaking up she bursts into tears and says she loves me. That may be true, but I don't think I can bear it much longer. What should I do?
