Hi..Jackie...you sound very stong..you know what you have to do and say or not say..now put the plan into action..remind yourself that it does not mean the end because he moves out...it means that the two of you can have some breathing and thinking space...I had to smile as I read KAW'S response to you..he has a way of making you see the light..an easy way!!!
Keep taking care of you..I don't know what to say about your kids and their comments..are they old enough to explain that the two of you need some space? I am sure it is extra hard with young kids...my kids don't say to much..my dd (almost 21- who adores her dad...and who sat with tears streaming down her face last fall when he told them he was leaving)one night when I was talking to her about wishing he would just let me know something..she turned to me and said"Mother..let him be..when he figures out what he wants, I am sure he will let you know!"Well ok..I have heard that so much this past year..I just want to scream..and the only way I am going to find anything concrete out is to point blank ask him, and that scares me..I don't want to hear what I don't want to hear..so I wait...
Keep venting here..it does wonders to come here and have a good cry!!
