No one can tell you: Clearly you are not content and feel unable to find a solution for changing him. I think it would be a mistake to trust any 'yes/no' answer to your '?'. It might be the way this will go, but there may be other options too. Try to find a therapist to help you think t through and perhaps provide or refer for couples Tx. Be patient as you seek a solution - it will help.
