Exdh and I have a reasonable coparenting relationship. He has a new partner (for about 3 years). Kids mostly like her but recently tensions have ramped up just because the DC are getting older and want Ming more of a say in arrangements which has led to some slanging matches between there is no love list between DS15 and GF.
He came home last weekend sobbing and various snippets of info have come to light: e.g. GF telling DS15 that he's fucking selfish for wanting to come home (even tho there have been many times when he's stayed over and not really wanted to etc), but the worst revelation is that he recently overheard a convo between GF and exMIL slagging me off while my kids were there on a visit.
There is no love lost between myself and exMIL as I was never good enough in her eyes (when I was married she would phone DH and slag me off to him etc) but I've never stood in the way of the DC having a relationship with her and have tried not to let my personal opinions of her get in the way if that.
However, after things blew up with DS15 and exDH he has confirmed that DS15 was accurate in his recall and that the GF and exMIL were indeed slagging me off in earshot.
DS15 doesn't want to see her anymore and doesn't want to sleepover at his dad's any more and I will allow the other two to make up their minds too, without too much influence from me as I want to be fair.
But AIBU to REALLY not want them to see his spiteful poisonous mother (she spent my wedding day telling everyone and anyone who would listen how much she hated her partner so has form for this sort of behaviour)
Am I being a precious snowflake? Wwyd?
