Good decision but make sure you do the following:

1. Keep an even keel when relating to your ex-wife in front of your daughters. Be civil; act like friends.

2. Keep in touch with your daughters and do NOT make them be messengers to your ex-wife.

3. Send money but send more love than you do money.

You should be okay. Keep your chin up and remember to be a responsible adult setting a good example for your kids.
