I have tried to talk to him, but he feels like I'm making a big deal out of nothing. He doesn't see that his actions at times are destructive to not only himself but others. People label him as a "hothead". He really has no real long term friends. He drives people away with his behaviors. There is a reason he has never been married. His mother tells me all the time that I have calmed him significantly... (I hate to see what he used to be like!) and that I am very good for him and that he truly loves me. However, she does also tell me that he is very similar in his mood swings to his father who has been diagnosed bi-polar. I am just at a crossroads. I love the times he is happy and in a good place. He's sweet and charming and generous. But the mood swings are tough on me. I walk on eggshells even though it doesn't help. It may be something he perceived I did or someone made him mad at work or while he was driving... you never know what will trigger it. I do need to make a decision as part of his issue with me lately is that I won't commit to moving in or planning marriage as I am scared. He feels like we have been together long enough that we should be in the next phase of our relationship. He says that he loves me and that should be enough.
