Ex has recently started having court ordered contact with DD3 and DD5. He's been having contact with DD5 for a few months but has only recently met DD3.
It's not going well anyway and I'm really irritated that he is taking DD3's nickname and changing it to something childish and offensive. Best example I can give is her nn is Betty so he's calling her Sweaty.
I don't think there's anything I can do about so it's more of a vent tbh!
