Thing is, being nrp is an utterly shit situation.
imagine being made to live apart from your kids, especially if they’re young, and only seeing them every other weekend.
you would plan on making that time amazing, doing things you wouldn’t normally do, and avoiding arguments and stress. You can’t maintain the same relationship as you do with someone you live with.
i dislike the “disney dad” thing as I think it’s an entirely normal response to the nrp situation. If you do normal boring shit or pull them up on behaviour constantly then you worry they won’t want to come.
i saw my brother go through it and yes he was a stresshead in the run up to a visit because he hadn’t seen them for ages, hated the fact they were rapidly growing away from him, that he couldn’t keep that relationship that you get when you’re there every day, reading bedtime stories and helping with homework. He’d be stressed about all the plans he’d made, would they want to go swimming, would they eat the food, should he let them have macdonalds? Also aware that they didn’t have their own rooms and all the computer consoles etc they were used to- he was living with parents as he couldn’t afford a place where they could stay.
how old are your dc o/p? It may get easier as they get older and can do things with the step dc. You could take them out for a few hours and leave him to it, spend some quality time yourself.
