Please listen to the posters. The advice is extremely spot on. You have to step back and allow your wife and daughter to work things out between them. This is their bridge to rebuild.
If you get in the mix and something doesn't work, one or both of them will resent your interference. Leave them to rebuild the relationship. You didn't break that relationship, therefore you can't fix it....but you can listen when your daughter speaks to you about it, but think before jumping in with advice.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
