you need to ask yourself are you having these feelings because of how he is treating you?? Or is it because of your OWN fears,doubts,etc.Fear can be a horrible thing.It can destroy the best of relationships.However,if you are being abused,of course then the healthiest thing to do is walk away.I wish you well,and hope things get better for you soon.I should add,if this is an ongoing problem for you,you may not be able to conquer it by yourself.You may need professional help and there is nothing wrong with that.all the best.
