It sounds like yall are making some great progress, be cautious but not cold. I know the temptation to repay some of the hurt is there but that will do nothing but hurt your M.
It is great that yall are in C and seeing a therapist for his issues! Im hoping that yall can get your life back in order and your R and M back to where it should be. Its a long and hard road but it can be done, the hard part will be rebuilding that trust, scary to be certain.
I will keep praying for yall!
