Always assumes the worst...

My boyfriend is on medication for ADHD...has been for years, so I knew he carried the diagnosis before we began dating.  I didn't, however, realize that it would have such an affect on me and our relationship.  Or I guess that's one reason I'm here...to see IF that is a reason for the struggles we face, or if the two things are completely unrelated.

My bf constantly accuses me of looking at other men, when I am not.  I am completely in love with him and think he is the most attractive man on earth (to me), and haven't even thought about looking at others...but still, I am accused.  When this happens, it is almost always followed by hours if not days of him completely ignoring me...no calls, no texts, if I am around him and am leaving to go somewhere he won't even acknowledge my departure with a simple goodbye.  Nothing.  I really don't understand how or why a person can do this to someone they claim to love.

Anyway, I guess I'm just looking for any thoughts on if this is truly ADHD related, or if he has much bigger issues in play...

Thanks to anyone who has thoughts to share.
