Yes, it's an amazing process as you start off wondering how you're going to get anything out of it, but the counsellor leads you down various paths and you and our H will have a number of eureka moments where you realise that actually this or that was wrong and this is how to put it right or that even though you or he thought one or the other was in the wrong over something actually it may have been your own perceptions etc
Ours went back to childhood to see how out upbringing affected our outlook on relationships now.
We had one major incident which prompted me to insist we went to relate, and I was surprised that very little of the sessions referred to that incident, it was all to do with how our behaviour and reactions to each other over the period of our relationship had lead to that incident occuring.
I so recommend going. I was actually quite sad to stop them!
