First, don't be fooled... it takes TWO people to argue. Does he not think that he plays a role in that? He also sounds either guilty or insecure by being so suspicious of you, unless you've given him reason to be. That's my two cents...

I don't know how long you guys have been together, but trust me, you don't want to make it work with someone who can't do any self reflection to see their part in the arguments. I still love my husband even when we argue.
