Is it wrong that each time my girlfriend and I fight I end up thinking about long I'll still be stuck with her, because of how much time is left on our apartment lease.
Why would you want to your girlfriend to leave you and where you live?
I get angry with her for being so angry at me.
If you and your girlfriend are constantly angry with each other, then it might be time to consider ending the relationship. Living in a place where you're constantly fighting with your partner is not healthy for either party.
I guess you are right. I will try to get over her and move on.
I think that's a really good idea. It'll be much healthier for both of you when you don't have to deal with all the fighting.
