Kim, hang in there. Guaranteed, just as you are unsure of your feelings right now, as they cycle yet again, WAH is having the same feelings.IMHO, that is why he is telling you all about his love life. He wants you to react.
I cannot imagine how hard it would be to have to hear it all, esp if you have to see him at work as well. You are going great guns, keeping it all together under those circumstances.
I hope you had a great weekend, watching the finals and spending time with your kids.
You are going to come out the other side of this so strong. You may save your M, you may decide you don't want to. But either way, you are showing yourself and your kids what a tough cookie you are, and that is inspirational.
