I don’t see this thread going well. But anyway...
If I’m honest, it wouldn’t bother me if I never saw my DSC again. Nor do I think it would bother them in the least. I don’t miss them between contact visits nor am I disappointed if a contact is rescheduled or missed. I generally feel quite detached from them - they’re like a friend’s children who come to stay regularly more than anything else. I’m kind to them. I help DH with them, and facilitate him spending time with him (in ways he does not reciprocate for me). But, I’m not really fussed about them being here.
Maybe I’ll feel differently further down the line. That would be nice, I’d imagine. But I don’t know. I can’t imagine ever feeling like they’re ‘mine’ in any way at all.
If I’m really, really honest (uncomfortably so), there are times when I might be pleased to some degree to never see them again. That is much less about the children themselves though, and more about the complexities of things and DH’s attitude and behaviour around his children being here (and also not being here).
I’m NOT the evil stepmother that I’m sure to be painted on here though. I fully recognise the centrality of his older children in DH’s life and I have no intention of changing that. In fact, I have seriously put myself out in lots of (quite major) ways to ensure that DH can have as much contact with them as he can negotiate with his ex (to the extent of completely giving up my bedroom for about 8 weeks at one point). It’s just that, personally, I don’t feel any great desire to see them.
BUT, I feel less uncomfortable about this because I know that DH would not be upset if he never saw either of my older sons again (or any member of my family). He may even be actively happy about it (not just ambivalently pleased).
It would be sad for DS3 though because they are his half siblings. But he’d never see them if DH were to die. In fact, I would imagine he’d have very little contact with DH’s family who show little interest in DS3, and seem to see the other children as his ‘real’ children. Neither of DH’s siblings have seen DS3 - not even on a video call; MIL has visited once, barely heeded DS3 while delighting in seeing the DSC, and never even asked for a video call - she speaks to the DSC pretty much every single time DH takes them out in the car without us though. So I’m pretty confident I’m right in thinking this.
