I think there are two types of ex.
There are those who keep their children away for legitimate reasons, and then there absolutely are those who keep the children away out of spite and bitterness.
I don’t think that we should dismiss the fact that psycho ex’s do exist, however, the response from the father in these instances is also crucial.
I have a friend who had an ex who deliberately withheld contact. Time and time and time again. But instead of walking away, he took her to court, and then back to court when she broke the court order, and again, and again. And when the DC were old enough they decided of their own accord, one by one, to live with him, and now that they are adults they are all NC with their mother.
Your dp’s ex may well be a psycho. But there is a separation between her being a psycho and his disinterest in having contact with his DD.
There are only two reasons why this could be the case.
Either he sees the child as an extension of her mother (have seen this before) and as such wants nothing to do with her, Or alternatively he really isn’t bothered because he now has a shiny new child to replace her.
But if he cared about his child at all he absolutely would go to court. There are 0 legitimate reasons not to. And by staying with him, by affirming his decisions not to go to court, you are backing up his belief that not loving his daughter is ok. Perhaps because deep down you’re happy with your own nuclear family now that you have a baby of your own?
I mean from your perspective you could walk away from him at any time, stop him seeing his child, and you know he’d never bother with her again. If you’re happy with that thought then clearly you support him and don’t feel you have to give him a hard time.
But I don’t imagine this is the first time she’s withheld contact and he’s just done nothing, and yet you had a baby with him.
Personally any man who didn’t see his kids wouldn’t have made it over the threshold into my life let alone into my bed.
But the bar for some women is clearly on the floor.
