I agree with caretaker that you really do not want your old life back. I thought that too for awhile, but there is really no going back anyway and even if you could it would not be the same. It took me a long time to get over a broken heart and put my life back together even though my ex-husband was cheating on me with the neighbor and made my life hell-on-earth.
I am remarried, an no things are not perfect. They never will be regardless, but I love my husband dearly and am willing to deal with or put up with the rest. It took me awhile to realize the dream I had when I first married was not reality.
If your daughter is in high school, she will begin to more distant and her friends will occupy the focus of her life. It is what we human females do at that age. Sometimes a mother is lucky to have any communication at all. I suspect she still loves you though, just wants to be more independent.
Your new husband sounds like a keeper. He is probably right about moving back to your old house. You really can't go back, but you do have an opportunity to build a new life in a new place that has a chance of being better
