<human>: We fight for a week or so at a time, then have a peacetime of about two weeks, then we fight about the same old things. Mainly it is about how I get upset she doesn't put the kind of effort that I do into our relationship. However lately she starts most of the fights about extremely petty things. Ex: How I snapchat other girls who I've been friends with for a long time. I don't get angry when she hangs out with other guys. More or less we were happy until about the year and three month mark then we've been fighting this way ever since. She brings up something petty then I get angry and she says I don't appreciate what she is upset about and then it turns into a huge broad argument about our relationship as a whole. I just feel like there are so many deep rooted unsolvable issues we have. I always told myself as long as we were happy 4 out of the 7 days of the week, it was OK. I love her, but this is really getting to me. I feel like I shouldn't be this unhappy at this age. She is so petty and I try to be receptive but I can't anymore because the fights are becoming so frequent and intense. She refuses to apologize for days then suddenly she realizes she was wrong and we are at peace then the cycle begins all over again. I want to break-up but I know I will be so devastated. How can I fix this, it is making my life a living hell between college and two jobs?
