I'm going to break up with my girlfriend of 2 years
What's making you want to break up after all this time?
I feel that she has never considered me when making decisions in our relationship.
That sounds really serious with how long you've had the relationship. She may be really disappointed, but you have your legitimate reasons.
It's pretty much just going to come down to a fight. I mean, we fight all the time. We're more like enemies than lovers. Besides, I'm still kind of mad that she didn't support my decision to play Counter-Strike full time.
Oh, well this additional information changes the situation. It seems you're not in a healthy relationship, and it might be for the best to break up.
