Sorry to hear you are going through this, right now

I agree, that your personal T, may not quite be the better choice for couples counseling.

Not sure of your ability to finance marriage counseling. Perhaps a referral from your current T. Looking through the phone book. On-line research, I've heard good things about IMAGO couples therapy.

There's possibilities. It just can get pricey. I like what Christine^^^ wrote, about that type of attempt to work at things, when money was an issue.

Will your H, be a willing participant, at working on his half? You are already in T. What does your T, say about the desire to divorce?

I'm all for, trying to do what you can, before actually leaving it all behind.
