Is my hope KILLIN me? LBS; Trouble detaching. HELP

[BlindTEENA]

Ive read several articles, part of the DB book, post on this and other forums, the 180 rules and they all advise that giving a WAS the space that he/she desires is neccessary. My husband had been out of the house since 2/1 and at first I was doing ok with it. I tried to GAL; hung out with friends, started working out again, got a job etc. He actually called and asked to come back home and I thought wow; giving him space really is working. However shortly after he started mentioning divorce.

Now is staying with his mom but is now looking for an apt. Im afraid that once he moves into his own place, he'l never come back home. He has been talking to women and has been out on dates; seems to be moving on and Im here crying everyday, and hoping that he comes to his senses. I have called him and pleaded with him on the phone to at least try and make our marriage work. He said he doesn't see us reconciling right now. I know this was the wrong thing to do but I couldnt help it. Im still hoping to work things out but is my hopefulness prolonging my grieving process. I don't know if Im in denial or if telling him how I feel is a good thing. How do I get to a point where I expect nothing from him yet DB? Please Help! Im having such a hard time detaching. We talk in some for or fashion every single day!
