I don't know sawks you met her a week ago and you're already in a R and have met the kids. This sounds like really shakey grounds. Talk about rushing things!!!
I'm going to be completly honest with you and tell you that I honestly feel sorry for you that you are unable to have enough self-esteem to be by yourself long enough to get like yourself a little better. I know that you have been S about 4 months but you were trying on your M just 2 weeks ago so that is actually how long you have been by yourself not the full amount of time you were S. Plus you still live with your W.
I hate to seem so harsh but I am just calling it as I see it. And the fact that kids are now involved too makes it even a stickier situation.
