If I had to do the tightrope walk of "the correct level of involvement" that most stepmums seem to have to do I doubt I'd be as happy
NewLevel has it for me with this ^^
I often find the comparison between step dads and mum's unfair because often the expectations of them are so far apart.
I know far more step father's who've been allowed to be involved in a parental way, been allowed to develop those close bonds, it's often step father's who are in situations where the other parent isn't really around as much or not at all. That's rare for a step mother really.
It seems to me that step mother's have a much more impossible task a lot of the time of being involved but not being at the same time, of loving like their own but also backing off when it counts. Of treating completely equally to their children but only when it comes to the 'good bits' i.e. money and treats.
This isn't always the case of course, I know that. But ime there seems to be a much much harder line for step mum's to tread than step dads. Quite often it can be down to the other parent. I don't think many mum's like the idea of another woman having any sort of maternal role in their child's lives but at the same anything less is seen as cold or heartless.
In my own situation, my kids step dad doesn't really do anything for the kids. He's good to them in the sense that he's kind and they really like him. But he doesn't really do anything practical, he's never looked after them alone, never taken them to school etc...
But me as a step mum, that seems to have just been expected of me and just part of 'being a family'. Helping out and mucking in but also not 'too much' either. It's complicated and at the start could be messy.
It's easier now, DSC mum has accepted me after a bit of resistance at first and we actually get on okay now, she comes in for a brew and we chat very easily. I actually think we'd be good friends under different circumstances but the slight undertone of awkwardness is still there.
I'd never get away with the level of 'just being a cool fun adult with the DC but not actually parenting' that their step dad does. Everyone thinks he's marvellous just because he plays a few games with them and makes them laugh. But hey ho.
One thing I will say is all of my gripes with being a step parent aren't anything to do with the kids themselves. That's the sad part. It's always the adults that ruin it imo.
So I'm not miserable, I'm not unhappy. I love my DH. But if I had my time again would I choose it again? I'm not so sure tbh. And I'd probably be advising any daughter of mine to avoid the situation herself.
