Hi lost, sorry to hear you are feeling down. Good for you for working! Hopefully it will be fun and will take your mind off your sitch.
Reading through your thread, I see you are doing the same thing I did for a while . . . you are analyzing your H's every move. That is going to keep you on the roller coaster. You have to choose to get off. There isn't one single thing he does that is going to change this sitch. Some things are promising signs, but you have to refuse to attach any expectations to them, or you will likely end up disappointed.
It sounds like you have not accepted your reality right now, and where your H is. Stop poking at him to see where he is. If you have another bad dream about him, keep it to yourself. Accept that right now, your H doesn't want to be married to you. I know that seems harsh but you have to do this or you will just be hurt again and again.
As far as kids are concerned, it is not their job to be understanding. Right now, they can obviously tell something is going on, and that is probably hard for them. Why is Mom acting different? What's wrong with Mom? (BTW, why have you not told them anything? They are definitely old enough to tell something is going on, and they may be angry when they find out you kept it from them.) So you need to be more understanding of them - this is probably confusing for them. Then, once you tell them, they will have their own feelings and hurt - so no, they are not there to be understanding. You are there to understand them. I know it is hard when you are hurting so much, but don't go to your kids for support and understanding. They come to you, and you go to your friends/IC/this board.
Get going with that GAL - don't lose your resolve! It is sooooo important for you to heal and keep moving forward.
Hang in there, you will be OK!!!
