Dd (6) has met at least 6 of FIL'S girlfriends.
He changes relationships on a regular basis, is never single, and is unfaithful to his girlfriends. This is his personal life, but aibu to say I don't want dd to meet any more of his girlfriends? This is on the basis they are never around for long, and it is pointless her forming relationships with them, and I don't want her involved in his frequently changing relationships.
Dh think I am bu, and it has caused a lot of arguments. FIL refused to come to dd's birthday party unless he could bring his current gf.
