My cousin has two children. (Another due in a few months)One with his current partner and one with his previous partner. He's practically abandoned his first child(7 years old) in favour of the newer child(3 years old). He seems them just two or three times a year. It's recently emerged that some of the information he told us about his ex and first child is complete nonsense and it's him who isn't making the effort.
His ex could be difficult(From experience) as can he and they were both pretty young when the baby arrived and spent more time taking shots(metaphorical) at each other than doing what was best for the baby but his ex seems to have matured a lot and is a great mother now. Unfortunately he seems to be focused almost solely on his second child. And the one that's on the way.
AIBU to not want to have much contact with someone who drops their first child in favour of the second? It will be awkward as we've a large extended family but I find it sickening that he cares so little for his first. The only other trouble is that I don't want to alienate his other children because it isn't their fault that their Father is a selfish twat.
