this would be a good subject to discuss with a t. i was in a similar situation earlier this year and i started seeing a t. he pointed out that the reason i wanted out of my marriage was that i have trouble letting people close to me. he suggested some couples therapy, which has been extremely helpful for my husband and me--it has helped us both understand each other better and it has helped me figure out how to meet my needs in the confines of our marriage instead of focusing on how much better things would be if i were single. i don't know your background or anything, but seeing a t about this certainly wouldn't hurt.
