<human>: My gf (23) and I (24) have been dating for a little over a year and a half. We met in school and both graduated last year. Before I start, she is a wonderful, caring and beautiful person inside and out. I just don't know if she's happy with me any more.

We started dating our senior year of college and we were both carefree, happy people. Started as friends but it moved to something more. Things were great for a long time but since we started working, she gets easily agitated and angry. It gets to the point where I don't even want to be around her because she tends to take it out on the people closest to her. She never used to be like this and I figured it would take a couple months for her to get used to working 40+ hours a week. But it's been almost a year and if anything, it's getting worse.

She has major problems dealing with stress and has stated multiple times over the last few months that she's not happy with anything. I'm a very patient and loyal person so I've helped her through it but like everyone else, I have a breaking point. Sometimes I just want to pick up and leave because I get so angry that she doesn't seem happy with me anymore but I don't have it in me to do that. But it's getting to the point where she says at least once a week that she hates everything about her life. I know she loves me and I love her but if she's not happy, what's the point?

I don't want to ramble on so if you guys have more questions feel free to ask. I would appreciate any and all advice on this. Thanks!
