Hello, this is Kitt. I so agree with the others who have posted.
You are a worthy person and deserve respect, so do not ever think you are not good enough for "him".
I know this is difficult for you and you feel sad, but trust me, if he is treating you like this now he probably would not change a lot in a long term relationship. Do you want to tie yourself to someone who cannot be counted on to be honest and forthright with you?
Take care and keep posting here. We care.
