I'm sorry to hear you're having such a bad time. As others have said, this is HIS issue, not yours. Not only haven't you cheated on him but you've taken all the possible precautions you can to make sure there isn't a HINT of impropriety on your part. You've shown him that nothing has gone on and he still doesn't believe you. He obviously doesn't trust you. Unless you've done something in the past to give him reason to suspect you or disbelieve you then you have NOTHING to reproach yourself for.

In my opinion his behaviour is out of order and I suspect that all those words that he used against you are really how he feels about himself. I know it's hard NOT to take it personally when you're called things like that but please try.

I hope that things improve.

Take care and good luck *hugs*
