I have been through this twice, and it drives me nuts!! She is just being selfish right now and if they are gone and seem distant, there probably is someone else. I don't know what to say right now other than feel bad for you and feel your pain. When kids are involved, that is the worse part. You need to be strong for them. They will need you more now than ever. If you ever need to talk, PM me and I will try to help.
