I am not going to be your friend when I finish here but I need to get this off my chest. I have been in my situation for 1 1/2 years now and I have finally accepted the fact that my H is not with me right now. It doesn't mean he won't ever be with me again, just not right now.
I am not going to sit around and make myself angry at him. All you are doing by going to his myspace or any of his relatives myspace is getting yourself in an uproar. The best way to get on with your life is to let go of anything that has to do with him. Don't snoop, don't call him, don't act at all interested in anything he is doing. The more you show him that you are angry, the more he will play the game. If he knows you still want him then he will continue doing as he wants. He knows he can "have fun" and you will be waiting at home for him when he gets tired of the OW.
You are sending negative vibes to your daughters. You may think you are keeping them inside but kids are smart and they can sense things.
Until you can accept that your H is not home right now then you can't do for Emily. You need to let go for yourself. You need to do this for your sanity. Once you start feeling good about yourself again, then you can start living your life again.
You mentioned if you go somewhere with your parents you are bored and end up walking by yourself. Maybe it is you that is the problem. Your attitude on here is so angry and violent. I know you are not really that type of person. Pain and hurt can cause the worst to come out in anyone. In the beginning I hated being around anyone because I knew they all thought I was crazy for not giving up. They still make me feel that way at times. I don't let them get to me though. I finally told my mom after the last time she said I should file myself to just mind her own business. I told her if I wanted to live in limbo for the next 10 years, it was my life. She understands now.
I know my situation is different because there is no OW involved and my H talks to me. (Then again, we have been apart longer) We have had time to adjust to everything. He has never taken things from the house either.
I hope you don't take what I say the wrong way, I just want you to be able to let go of some of your anger. I think it will help you heal faster.
