which is none of my concern specifically as he is not lying to me and given they got together whilst I was pregnant, I don't have much sisterhood connection with his current partner.
However, the background is important.
We have two children together. He has never lived with us and is totally unable to accept proper responsibility (across the board; work, home, children, relationships). He is controlling and manipulative with women and has (certainly historically and probably still) numerous ongoing affairs. I have suspected NPD for some time. I got out eventually and am enormously relieved that he is no longer my direct emotional responsibility.
For about 4 years I allowed him access on demand to the children here at my house. He lives at the other end of the country and so to see them it would have meant him staying in a hotel. He pays a good amount of maintainence and so I was reasonably ok about facilitating it on my home turf despite it being awful for the last 18 months of that period (the time since we finally split up). This has meant him being here every 3-4 weeks or so for a weekend.
In the middle of last year I finally allowed the children to start visiting his home where he lives with his new partner. We agreed the terms in advance. This included that we wouldn't introduce our children to anyone we weren't in a proper committed relationship with. He grew up in a home where both parents brought in a string of new partners and I suspect some of the damage to his mental health has been caused by this. I have repeatedly said to him that if there is anything going on which would jepordise his ongoing relationship which would ultimately cause upset to the children when the inevitable break up occurs he should think twice. He has assured me all is fine.
Since then there have been at least five occasions when I have had cause to believe that he is seeing at least one or two other people as well as his girlfriend. I really need the occasional break from the constant childcare and full time working but I am niggled by the fact that he is being potentially careless with my children's emotional connection with his new girlfriend. She seems a really nice girl (significantly younger than him) on the face of it and I know that it isn't any kind of open relationship.
In turning a blind eye to it all am I in any way complicit in the potential damage down the line? I feel really uncomfortable about the fact that he is still acting in this irresponsible way. Should I stop them from going? I sort of think I will just end up having to explain that he is what he is and that, although he loves them, he has some issues of his own. But then I wonder if I should protect them as much as I can.
Sorry this is so long - am really grateful for anyone who gets to the end of it!
