I would try to keep my heart open and keep lines of communication open. Give her space but try to be there for her. In the end, you always want peace of mind that you didn’t close the door on your kids. Write a letter if you feel you need to. Or just periodically call, send cards or small care packages. Hang in there. I’ve been there and it was a tough ride but I personally think it’s best to ride it out and just give it time.
