Good job making the parenting decision- H probably wouldn't call you back if you called to ask him anyways!
Wow- dating kids! That thought scares me- and doing alone sounds even scarier to me. I do miss the backup parent- not that he did much but to not feel so alone with the kids!
He is being a jerk not calling his D- but so typical!
My H was the same way - couldn't face my family. But he does attend the stuff that isn't at my moms. Maybe tell your H- for your D it would be nice for you to go to the birthday and "church thing".
It is easier when they are away- don't have to be hurt by them as much- kind of forget all of it more!
Glad to hear you are working on the financials- eventually you will get sick of doing it and just finish- the expenses will keep changing but it is ok as long as you have a good estimate- ideally a high estimate!
