I have been with my girlfriend for 6 months now and everything has been great. We love each other very much and have a good relationship. Its just sometimes when shes comes home from her work she is stressed out cuz her working conditions change alot and the supervisors sometimes give her a hard time. Sometimes when I come to see her at her house after work she is really bummed out and doesnt want to be bothered. How can I make her feel more happy to see me? How can I get her out of a bad mood and feel better?
