Wow, this is me also.  I asked him to leave in January, after many many months of trying to get him to go to counseling.  He has been gone and this last week started to really feel .... in shock?   I dont know. I do know that even though I still love him I cannot go back to that way of living. My house was total stress and negative emotions when we were both here together.  I have also been dreaming about him the last two nights. And not bad dreams. 
I am sure this will pass.  I pray about it a lot.  I dont know if just ignoring the feelings help or not.,

scarlet, i find that some days are better than others. my soon to be ex is dragging his feet and living with the illusion that i will come back!!!! he wants us to go to mediation but has yet to schedule a date thru his lawyer, i feel like im in limbo. i really try not to think about it but, that doesn't work most days, i just want it over with so i can move on emotionally!!  i am currently living with and off of my daughter because i can't find a job,and am trying to go back to school. until you acutally have to live with one of your children, no one knows how really bad that makes you feel to have to depend on them. It's supposed to be the other way around and i thank god for her and her boyfriend cause i don't know what i would do. so try to hang in there and write me anytime you like

I am completely in the same boat as you KLC. I have been doing fine until last week. I also was the one to leave and have been struggling with guilt etc.But  last week I started to feel so alone and sad although I know it was the right thing to do. I am trying to be rational and replace negative emotions with positive ones. I just wish I knew how long it would last and then I think I could get through.

Men have been struggling with how to tell women to deal with their emotions for centuries with no luck. I know this is a long shot, but I am one of those hopelessly optimistic people...try REASON AND LOGIC for a change!  You will get further by trying to figure out a problem rather than screaming or crying at it.  I wish this worked with my ex, whom never listened to reason and wasn't swayed by facts. If the world was run through emotions, everything would fall apart and be pointless, because emotions are just feelings, not facts.  Try looking through his eyes for a change, walk a mile in his metaphorical shoes, and for a moment think rational and moral thoughts.
