Insecure about my life & love, Mood swings problems. Can someone help?

I understand where your coming from. My bf is kinda the same way. When he starts having one of his mood swings it puts me in a bad mood but I am the type to talk things out. Some things I tell my boyfriend is when you know your getting in these moods to take a minute and step back. Think about what your going to say cause it might hurt her and you know you don't wanna do that cause it hurts you. If need be leave for a while and cool off. Think long and hard about your feelings and why you are feeling the way you do. Then come back and sit down and talk things out cause breaking up and getting back together is only going to last so long before shes done and if she really means a lot to you you need to work on controlling this issue.
