Our relationship couldn't survive. We went to a couple sessions of counseling together....not very productive. My counselor has agreed to see us together again, but only if we have a specific topic, such as "How are we going to handle seeing each other at the children's school activities". She said it would be useless to try "marriage" counseling at this time for the very reasons you describe.
I think if you continue your personal growth through counseling and he does not you will find that you aren't moving forward in parallel lines, but rather will be going in opposite directions. IMHO it will be very difficult to have a close, emotionally fulfilling relationship with someone who is stagnant and who's heart is not open to change and grow with you.
