at the moment i have one of my girlfriends living with us, and she has a 2 yo son. i have no problems whatsoever with my gf, but her child is horrible - and as much as i feel like such a bad person saying it, i can't stand him being here. he has major behavioural issues, nothing diagnosed, so i'm not having a go at a child with issues, but he is so naughty. almost vindictive.

i don't want my ds to get any of the traits that this child is displaying, and i'm getting increasingly resentful of having him here. what do i say to my gf? i don't want to ruin our friendship, but i can't stand him.

and i'm not saying my kids are perfectly behaved, they do all the normal kid stuff, but it even brings my gf to tears the stunts that this kid pulls - he spits in her face when she says no, he slaps her, he screams constantly for no reason, he's just plain nasty.

how do i bring this up with my gf, that i think maybe she should move out??
