I agree with the advice the others have given. You need to spend some time here taking care of yourself. What is done is done with him, you probably learned a valuable lesson and if you really think about it you got out of it quickly and without a lot of long term trauma. Many people who make that sort of mistake then get stuck with years and years of pain and agony. So at least you guys broke up quickly and now you are free to lead a full, happy life with greater knowledge than before.
A person can just about always find happiness where they are, if they *want* it. There are people out there with little food, no real home, little possessions who are completely content. Compared to them, us people with places to live and computers and jobs are kings and queens. So for us to be unhappy is pretty silly. We need to appreciate all the great things we have in life, and to treasure them.
I agree with the others too about your daughter being an adult now. Yes, it's hard to let go. The whole 'leaving the nest' is traumatic for ANY parent, be it bird, lion, or human. But it is a required part of life. In order for her to succeed as a happy adult, she has to be on her own and she will make mistakes. She will learn from them and get stronger. If you try to shield her and watch over her, she won't get strong. And since you can't be there forever, *now* is really the time to have her learn those lessons, when you are still there as a "last ditch safety net". But if you keep that net too close, she'll never really test her wings.
