Bloody h-ll. I'd typed out a whole response, which I think was pretty good and thoughtful, and then tried to insert a smilie.... Gone. I'm not sure I can catch it all again.
I'll start by saying that I said manipulation before opening the thread too. Knee-jerk reaction right now.
However, IMO, some one who is willing to accept responsibility for his action and the pain they've caused, accepts it across the board. If his actions have hurt one daughter, they've hurt the other daughter, too. I get that every child has a different personality and a different relationship with their father. But making up to the daughter who reaches out to him and not his other daughter is thoughtless and cowardly, at best, and manipulative at worse. It doesn't say that he's truly trying to change to me. IMO it says "I'm going to take the easy way to look like I'm trying to change."
Big hugs for you and your daughters.
