Before lockdown me DP and our DD had a great relationship with FIL he was a regular visitor and always on he phone to check on DD etc.When lockdown was announced he moved in with Bil and his family. Everything was great we facetimed and called regularly him regularly but when restrictions where eased and BIL went back to work contact between us and FIL rapidly dwindled. He was always to busy helping BIL's wife with things and busy with their kids anytime we called or invited him anywhere.
DD hasn't seen him for anymore than 10 mins at a time in over 2 months since he moved to a town 20 mins away with BIL when him and his wife split up. He turned up unannounced last night sat for 5 minutes and said he had to go he needed to pick up a Chinese for the ex wife and kids.
DD was distraught as she didn't want him to leave so I calmly explained to her that he lived further away so couldn't visit as much or for as long. She hit back with well how come he takes BIL's kids to school everyday and picks them up aswell. Then their at BIL's with him all weekend yet can only manage to spend a few minutes with me.
I queried that with DP when he got in thinking DD was probably exaggerating a bit but he confirmed that it is the case. That FIL is there everyday to help out. DD has come home today again quite worked up about it. She even asked if she's done something wrong and thats why he doesn't want to spend time her.
Would it be unreasonable for me to text him explain the situation and say that until he can treat his grandchildren equally he shouldn't bother visiting in future? As DP seems to think we should just forget about it and she'll get over it?
