His boys are 10 and 13 .. When they stay he allows them to eat constant junk into the night and they hardly ever brush their teeth... Last weekend they were here for four days and as you know its been very warm!!! On sunday it occurred to me that they hadn't showered so I said "have you guys showered this weekend!!? " To which I got an awkward stare and silence like they'd been caught out!!!! He's always been pretty useless but now it's getting to the point that I'm losing respect for him and don't even want to be home with them as it is making me so angry!!!! Yes I know that they can sort their own hygiene out but they clearly aren't and he will do absolutely nothing about it!! Yes I can step in but if I do I get told to butt out... Also they're his responsibility!! How do I bring this up without getting a barrage of abuse!!!!
