My girlfriend is negative and always has a problem
So, I've been dating my girlfriend for about 2.5 years, and I have noticed over time that she is just really negative about life and always has to have a problem. We both love each other and often do have fun together, but its most of those other days where she is always unhappy. She always fights with her mother, and if not her then she is fighting with people at work or with her friends. If those are okay then she is ether upset about herself or her life and lastly, if all else fails the constant pointless fights shell have with me. It never seems to end, its always seems like there is an issue that we have to deal with and I am just drained of listening and dealing with all these problems. I love her and have tried to make her happy, I even help her with a lot of her problems but, it always falls back into the same old pattern with no end. I know shit happens in life but, she seems to have a problem with EVERYTHING. I feel that I have started to become Depressed and negative and I feel like its started to affect things in my life. I need advice on what to do?
