Another one here pretty confused by some of the posts...
The fact is when DC's non-resident father is very involved it leaves very little room for the mother's new partner to effectively step parent.
OP has been co-parenting with her DC father. If he's anything like my own partner, her DP probably tries very hard not to step on any toes at the same time as trying to be as present as possible and not show it when he ocassionally feels like a spare part.
The fact he is not as hands on as their father doesn't mean he doesn't love them. And in this situation he has no choice but to treat his own child differently.
OP herself is probably unsure of how much she can rely on her DP as she has probably tried hard to establish a balance and boundaries herself over the last few years.
As PP said, blending families is so hard, it's a fine balancing act and every family is different. To say OP and her DP "should" be doing anything is unfair.
OP if I were in your situation, I'd want to know my DP was ready to step up to the plate and understands that he now has to change his role. Have you had a chat about this? Can you agree specific ways he can pitch in?
I'd also be loathe to change DC's schools. Mine spends 2/3 nights a week at their dad's and because of this I like to keep everything else as steady as possible.
But in this case, I'd be really tempted, especially for the younger 2. And they will have each other for support.
For eldest, I think they're old enough for an honest discussion. That it's going to be very difficult and talk to them about the advantages of changing schools. If they want to stay at the same school, they'll have to be prepared to go to after school club/breakfast club everyday, take the bus when they go to high school etc.
If your ex is going to be stopping child support, 30 mins burning fuel in city centre traffic every morning will be a significant saving to make.
I know it's devastating for the kids that they will see their dad a lot less and it will have a real impact on your life, but i also think there are advantages to having longer periods of time settled in the one house as a family
unit. Hopefully your family unit will become a lot stronger.
I can't believe people were excusing OP's ex's decision to move away and someone even said it would be acceptable if it was for work or a great opportunity etc.
How is this ever acceptable? How has the OP done anything wrong in assuming he would stick around to continue to co-parent and basing her own life decisions around that? She'd have faced equal criticism if she'd have settled her DP in as a replacement father and tried to prevent the 50:50 arrangement with their natural father.
Are mothers supposed to just constantly hedge their bets so these dickheads can pick and choose? Such a frustrating thread.
