I didn't go back through your threads, how old are you? Because it's sounds like you are in MLC.
I have to agree with someone here; your H is not going to say come back because I love you, just using "family" as a reason to get you to try. Frankly, I think it's cute that he did.
You need to drop ALL CONTACT with OM! What are you thinking? You don't really want him either, do you want to go through life going through one D after another? Better fix you! You sound very confused, not good time to keep OM in the picture. It's not fair to him or you.
Off the "bottle for 2 wks", big deal! Is he going to AA? Is he getting help? Are you his mother? Do you want to be? Because, he is treating you like one. Letting him stay with you? You must be kidding! Would you take anyone that you are friends with in? Your apartment would be full!
Sounds like you are using him being cold as a good reason for letting him stay!
Are you seeing a couselor? Not just a M one either. You need some help here. Let's face it, your life is a mess.
Positives~ Your H wants to forgive you, wants you to be a family! Hello! And you are comparing him to the OM! Is your H a alcoholic? Sounds like he is a great father, did I get it right D is living with him?
I see you as standing on a cliff, getting ready to jump! Better turn around and go back the way you came!
