No, I don't think this would be helpful, based on what you have said before. People, men in particular, don't respond well when you say to them, "you have a problem." Instead, I think you should let him know how serious things have become, how unhappy you are, and that you are thinking of leaving him. Then tell him that you think that if you both work on "things", that your marriage can improve and you would like him to go to marriage counseling with you. Have you suggesting counseling to him before (couples counseling, not individual therapy)? Maybe he'll agree if he knows how serious you are. The therapist can really help with communication, which I think is a major problem for you two. (Ask your "shrink" for a referral to a couples therapist.)

Best of luck.
