oh piss off, my kids don't need anyone feeling sorry for them thanks.
They're teenagers and understand that if they left something at their dads that i will get it for them, when its convenient to him.. and yes i do have a key to his house, but i'm STILL not going to just let myself in without permission.
My ex is a twat, but i'm still not going to just demand he stop whatever he is doing and pander to me/our kids demands because i haven't got enough respect for him to make it clear they will have to be patient, because its fucking RUDE to demand another person stop what they're doing to deal with a non-emergency.
I have to deal with him doing what the ExW does in this situation, as i said upthread, that being him messaging me to say "I'll be at yours in 10" to just do something random/drop something around for the kids, without any consideration for what i might be doing, and then scream at/abuses me when i tell him it's not convenient, and then feels he has the right to interrogate me on why i can't drop everything to pander to his immediate demand on my time.
Why the ever living fuck would i do the same to anyone else when i KNOW how horrible it feels to be on the other end of it?
wanting a specific pair of trainers when they already have 2 pairs at home is not a 'difficult' situation. I feel sorry for your kids if you haven't set them up with the emotional fortitude to cope with a mild inconvenience of not getting their own way the moment they demand it.
