Advice

I am in so much emotional turmoil at this point in my life. I am engaged to be married to a man who while convinced he has AADD he is unwilling to accept or understand my frustrations and feelings on this. He has told me on multiple occassions that I am the one with issues. I feel like I am losing my mind, Its like I am always walking on egg shells until eventually I erupt in a fit of anger. I don't know what to do? I love him with all my heart but truly feel like I need to find a solution to this issue or leave. Does it get bettter, how do I handle this situation?
