About to start CC

We are about to start our first session of couples therapy and I’m nervous. We are 4 weeks out from D-day and while we are obviously not in a good place, I think we are much better than I anticipated we would be.

We have been intimate, we have managed to go away for a weekend together with only minor fall out and I almost don’t want some external third party to come and set us back.

Can anyone with experience in therapy (IC or CC) give me some insight as to whether it helped or hindered you?
