If I were you, I'd want you be there to hear any conversations that went on. Him trying to coerce her into going back, any arguments, any name calling, anything he says about you...
That's exactly what I would do. The thing is, is he going back for the s** aspect? I think your daughter should concentrate on getting her own life into a rhythm and arranging with him to visit maybe twice a week to see if he keeps to a routine. His behaviour has been anything but supportive and there's no indication that anything will change. He can't just dip in and out of relationships, especially fatherhood, on an ad hoc basis. You need to have a proper talk with your daughter as she keeps going back and that's not doing her (or you) any good.
Wishing you the best outcome.
Agree with the above. The fact that she has even kicked out a few times and he has his mates round plus the possible cheating, all seems to add up to yes he’s using her for S**! He might even enjoy a bit of coddling from her …meals ready for him, etc, but once he gets fed up of that and wants his own ‘space’, mates and partying, …out she goes! With a baby he’s not going to find that happening, she will be too exhausted to possibly do either!! He will get fed up sooner! I think this needs to be ( gently ) explained to your daughter. With a bit of luck the new baby and tiredness will drive all thoughts of returning, particularly when you point out she will have to do it all alone herself then… ? You could even smilingly tell the ‘young man’ how exhausted you are being up all night with the baby’s crying and aversion to the cot!
I suspect that unless the baby is quiet and smiling all through his visit, he might realise himself that having her back is not on for him?
