Unfortunately some relationships aren't meant to last, but before making any concrete decisions, I only suggest you deeply consider whether the source or sources of the arguments aren't fixable. Working through issues is a viable means to keep a relationship going if you two are willing to do so together, but if you don't think it's worth it or there really isn't a way to fix the problems, then a break up might be the best solution. Regardless, i'm sorry to hear you're having problems. My girlfriend and I were going through a period like that as well a little while ago.

Thank you for the kind words. I just broke up with her. I believe it's for the best. It's a combination of her recent show of immaturity and her father catching us doing stuff in her room, there isn't a good way to fix that. But again, thank you. I hope you and your girlfriend are doing better.
