GGG- Your comment above about not being able to stand being alone I think is right on. He's probably grasping for anything to fill that void that he hasn't learned is filled by himself facing his issues.
My H's IC tells him ( and he has shared with me) that he should not try to have any new relationships right now as he will just try to " give everything" in the hopes of getting what he needs and have unhealthy, destructive relationships. Surprisingly he appears to be listening thus far.
Maybe your H entering counseling will help him to see he at least has issues. Of course actually dealing with them is a whole other story. ...
Hope the upcoming talk is good.
