This was the role that DP's wife had, and which he has now taken on. I worry that both DP and the children want a 'mother' but don't realise that the 'mother' is now DP. It seems ridiculous - but it honestly feels like there is pressure from the 4 of them for me to fill this gap, but there isn't actually a gap to fill, because DP has filled it?
My DH was a great single dad to his children, but there is no question that he missed a few things that were going on with the kids. And there are ways in which he wasn’t totally perceptive to their feelings at times (I don’t think anyone could be, all the time, so I mean no criticism of his in saying that). When their mum was alive, she played a certain role in the family structure, and there was no way DH could fill that in - and plus, she was their mum and they will miss her forever! Your DP won’t have been able, I suspect, to ‘fill that gap’, because the way he parented his kids and the way the mum parented the kids will have been complementary rather than identical, IYSWIM.
That doesn’t mean, of course, that YOU can or should fill that gap. That’s probably not a realistic goal for any of you to have. It sounds to me like you need more time to figure out what role you want to have - are you worried he is about to push for more - moving in together/marriage?
My relationship with my DSC is one that has changed over time and definitely goes up and down. They are teenagers now for a start and I have to remind myself that we'd have loads of the same issues no matter what our family origin. The kids have never wanted me to be a mother (although they definitely want me to do mothery things, whether that be in terms of providing for them or remembering their important occasions, keeping track of their friends and their ups and downs…some stuff they aren’t conscious of wanting, I suppose, but they do) – they are very clear that their mum is their mum, even now, and so it has been easier for me than for you, perhaps, in that I haven’t felt that they wanted me to step into her shoes – more the opposite, worried that I’d try to step into her shoes, so I initially had to try and reassure them that it wasn’t my intention to do so – but that I still was going to be family to them. I think you are in a much tougher place, at least for now, because the kids are so young.
DSD was very resistant to me being a part of their lives, while DSS was more well-disposed towards it, I think because he needed a female presence and a bit of attention. After losing their mum, he was much more set adrift than DSD…there is more to it but without getting into all the details, I’ll just say that he was glad to have someone on his team again. As far as what I mean by mothering – if he fell and got hurt, I’d cuddle him and bandage it up. He used to crawl into bed with me and watch telly and talk about his day. When we all went places together, he’d stick close to me. We don’t have that kind of relationship anymore, mainly I think because he is now 16 and has pulled away quite a bit, to where we’re having some behavioural issues with him, and I have been the ‘bad cop’ when it comes to enforcing house rules, etc. - actually, that is one thing I would really caution you about, to be sure that you and your DP are in agreement about how you will negotiate differences in parenting style, especially since you say you want to have your own - even if you keep some separation, you can't ignore the fact that sometimes you ARE going to be thrust into that role and if you don't feel supported, it is very tough.
DSD and I have come a long way and have a pretty decent relationship now that she is older. As well, having my DD brought us all closer as a family unit and it did make me more a part of the family as far as the kids were concerned, so I think you are right to wonder about how that might change your dynamic too. I have more problems with my DH and his lack of involvement with the kids than with the kids themselves, if that makes sense. Sometimes over the years I have felt that he was so exhausted by his responsibility to them, that when I was around he just ‘switched off’ and left it to me to deal with because he needed a break – fine up to a point, but only to a point. When I find myself managing all the needs of three kids (DSC plus our DD), I get pretty exasperated. There was also a lot of compensatory behaviour by DH - similar to what I gather from these boards happens with divorced dads - he let them get away with murder for a long time, because he couldn't bear to see them unhappy even in a trivial way.
