i've been with my boyfriend for 2 years and 3 months the first year went great and we seemed so happy together, we had a break and got back together again after a argument we had over a guy at my college. now we're back together the few months after the break when fine but now we seem to argue a lot more and he never seems to want to listen to me and what i have to say. he always ignores me for days and always tells our problems to a girl who doesn't even want us together.
what am i meant to do?
