I agree with Sage. I think I would just leave the other relationships in all areas of your lives together alone while you sort this out. I think it would show that you seriously want this to work out between you both first and would give you a fresh start where no one has asked the other for anything.... it would be understood that once the work you need to do is done you will work towards starting new relationships.
Therapy is NOT about someone telling you how you feel! This is NOT good therapy... therapy is about someone walking beside you while you figure your shit out. They are there to invite you to look at things that maybe you have missed and to dig deeper in issues and emotions that you have.... Your partner doesn't seem to have a clue on this and I suggest he do some research... as I also think you could use some extra help here.
