concerns i have are more current so sessions have been frustrating intense and exhausting for me. Counsellor advised we dont discuss outside of the session with each other.
I want to ask him wtf why with all of this resentment why are we getting along playing a loving couple is it all fake!
I would strongly advise that you bring up all of the above at your next session.
Do you feel as though your partner is taking over the sessions? I'm just wonder why the recent sessions have felt so frustrating and intense? Is it because the issues that you feel are important haven't been focused on?
It's worth noting that you both need to be heard equally (both by each other and by your counsellor). This may not happy equally every session - sometimes you'll talk more, sometimes he will, that's natural - but if there's a consistent imbalance I would be concerned and raise the issue (n.b. you may need to be open to seeking a different counsellor in order to resolve this).
A further point, echoing previous posters, is that you'll need to take each other's points of view on board. Even if you feel your DH is wrong, it doesn't mean that his feelings are invalid and don't pose a barrier to him. For your DH, the past resentment is a barrier that he needs to get past. For you, the recent stumbling blocks are a barrier. You need to remove both barriers, working together, before you can meet in the middle and go forward on the same path.
