Well, if he suggested previously, great ! BNow it's not your idea, and not about crriticizing him ( which he seems to fear ) but could become constructive. NO professional counsellor would tell you you are a crappy person ( which you are not ) nor allow him to do nothing but that. They would hear both sides. So, yes, you would hear some of his old complaints, but once he has expressed them, the counsellor can raise the point of these being old history, and why he feels they are still current, etc. This could be the way to find the solution you seek
