My friend has been in a relationship for over five years and they have two DC (age 3 and 1). Her partner has two children from a previous marriage, age 16 and 11. They both have good jobs and are comfortably off.
He is completely estranged from his Mum, sister and brothers and all his nieces and nephews. He gives no concrete reason other than his mum is “difficult” and they love drama.
His family all get on well together- go away on holiday together, Christmas, birthdays etc. they also all get on well with his ex wife so his older kids spend time with them regularly and speak very highly of them.
This doesn’t seem like a dysfunctional, fractured family, he is the only one estranged. His father passed away years ago, before the estrangement.
Mu friend believes his sister and possibly one brother too have reached out to him but he shrugged it off when she asked him and evades the question.
He’s made no effort to introduce his younger children to any of his side of the family and my friend has never met any of them.
Would this be a red flag for you?
