Divorced dads have a lot harder time staying involved in their kids' lives, even with they make every effort, keep every appointment, and ask for more time then they are given with them, post-divorce. I am that dad.
I'm excited to live through those times WITH my kids. And I will be 100% positive and 100% present for all of them, as long as I live.
I don't want to return to an intimate relationship with my ex-wife, but the intimacy we share in raising our kids is more important and deeper than any of our feelings of loss or anger. We have to get OVER our emotional divorce in order to get INTO healthy divorced parenting roles.
If I had it to do all over again, I'd probably argue with the counselor and my ex-wife and negotiate something a bit more even. You will be advised not to do this. "It's easier for everyone if you just accept this plan, it's been working for families for years."
Live your life as you would like to see your kids living theirs. Show them the adults they can be, by demonstrating the best that you can be. Anything less is a miss. Parenting and co-parenting resources come and go, theories of parenting and how do recover from divorce will change from season to season, but this truth never changes.
So much of co-parenting is about negotiation and compromise. We no longer have the same loving emotional ties to our former partners. We no longer have to make their urgency and priorities our own.
