I'm of the mind set that even if he refuses therapy, you should go for yourself, because this has got to be damaging your self esteem and self worth incredibly. And maybe when he sees that you are serious about this, serious enough to go to therapy on your own, maybe it might dawn on him to think about this issue a little bit more and how important it is to you.

And besides, if all else fails, you are taking care of yourself so that you will be stronger in the future, regardless of what happens or where life takes you.
