not grounded in anything specific about the bf

just doesn't believe in it

you a grown man? not family? shouldn't be around my kids if i'm not

seems especially relevant to is SILs' (of which he has 3) boyfriends

one of the SILs has messy relationships and it's probably good thinking on dad's part

but this one is the opposite, very stable, responsible and grown up. i mean there's a reason they want her watching their kids so often
