I'm trying to detach, but its so hard.

I read up on the 180. Usually, I am distant but when we talk, its serious discussions. He usually initiates contact: face-to-face, text, calls, etc. The 180 for me includes making more small talk and initiating more of the communication. I started this after reading about it here.

Last night, he went to bed early in DD's room. An hour later, I was going to say goodnight to our S and overheard him talking to OW. I listened to his side for a bit, he was telling her about his feelings, work, and our M. I was upset because he has this easy conversation with her (that should've been me). When we talk, he's short and rude and he has his walls up. I left. After 15 minutes, i went back and said goodnight to our S next door. H had the door opened and I said goodnight to him. Then we started talking.

He admitted that I was confusing him with my new 180 attitude. He then told me that he's sure he wants to be alone, not married. I said ok, but I was glad to see he noticed my change in attitude.

What else can I do?

As for GAL, I've started running on my own...
