This happened to me right after the For Sale sign went into the ground.
I was the one who initiated everything, too, but I was clinging to anything at that time. Again, trying to control the situation. We want to believe that each time will be different and he will change. I will always love my ex, but now I do it from afar where I am healing and taking care of my needs. You are doing the right thing for yourself and your children. I don't have any children with my exabf, but please know you are not alone!! Others will post, too in time.
