My gf of 6 months now has changed so much since i met her... At first she was happy and fun to be around but not alot is going on in her life and i understand that its hard for her but she is always in a bad mood and always snaps at me and i am really confused about what to do. I am thinking about leaveing her cause dealing with my own stress and she is putting alot of stress on me too. I really dont know what to do...
