Well if you and her dad do everything right she will pick well too and you'll be able to say, "We couldn't have picked better". My ex-wife and I divorced each other but not the kids. One of the few things she and I agree on is that we did a good job raising the kids inspite of the fact that we couldn't stand each other. We seperated when they were 11 and 9 but never worked against each other or tried to limit access. My ex and my new get along really well.
Sounds like your children were fortunate to have you for parents!
