If you do not go NO CONTACT, and the 'subject' of 'marriage' and 'your future together' does come up.
A simple answer:
"Since we are both working on OURSELVES, this subject needs to be put ton the shelf for at least a year."
Then change the subject completely. Repeat the above when he tries to go back to it and he will, lol Become a broken record.
Easier just to go NO CONTACT. That gives him ALL the space to work on HIMSELF.
