I dont know what to do
My boyfriend has been upset a lot because we keep fighting and hes saying I'm the one hurting and getting upset with him
Fighting in a relationship is hard, but it's something you can overcome if you try to discuss openly, sincerely but quietly about the problems that are making you fight. If you both have the will to make things better, you can try to sit down at a table, keep your calm, express how you feel and what doesn't go well, without accusing each other. The approach must be "how can we work on this and make it better together?"
If he refuses to have this talk, or if he keep blaming you for everything and he doesn't have the will to work together to improve your relationship, then you can consider if you would really be happy if you stay with him. I know that breakups hurt, but in the long run, an unhappy relationship and eternal fights would hurt much more! Sometimes breakups are simply our only chance to be truly happy again.
