How do I fix my relationship?

So me and my boyfriend are going on our one year anniversary and we love each other so much. Throughout the year i've had a lot of family things going on at home and i didn't feel comfortable staying there. My boyfriend opened up his home to me because he knew exactly what I was going through. He is super funny, and he really does take care of me. We always have disagreements and don't know how to fix them. I get really irritated because when I get mad he tries to joke and make me laugh so we aren't mad at each other anymore. Later I tell him that yeah it might be funny at the time but it doesn't fix anything. Its hard to get him to talk serious because he turns everything into a joke. I have a temper so i know i get mad easily and maybe at the dumbest things but i dint know how to control it when he just doesn't listen. Ive done therapy/counseling at school but since i graduated high school i stopped. does anyone have answers to what we should do about our relationship? Should we go out places more? Should we have times where we just talk seriously? Its my first real relationship and since before him i'd gotten hurt many times and my insecurities get in the way. ANSWERS?
