I'm in two minds about this one. Of course, the Wimbledon issue (and I remember the thread) is a no brainer. He was a fud to do that, and I'm afraid the very fact that he did, is enough to tell me you're not going to find it easy to get through to him. I can only imagine that he is so determined to be a good father he can't see the wood for the trees. I don't think it's personal against you per se, but he was being stupid about it.
However when you say
Since we've been back, she's only been with her mum four four nights and we've had her again for another eight in a row. I do find it quite claustrophobic. Like I barely have time to get my head above water to take a breath before she's here for another huge chunk of time and I'm back underwater again.
I did do a meh. I'm afraid that is what parenthood is like. For all of us. That's what it entails. None of us get a break. None of us get to pause for breath. I understand how much harder it must be when it's someone else's child, but that's what you took on. I often think it's a shame for step parents who haven't got kids of their own, because however much they think they're prepared, I think it can really come as a shock, just how relentless it is with children around. They haven't always got the parental bond to motivate them, so it must feel like an assault at times.
That's the reality of getting with someone who has children from a previous relationship.
Let me tell you this for nothing - if you have a hypoglycaemic episode when your own child is 6, you will have no issue with breaking off a piece of chocolate for him or her, no matter how faint you feel. You'll do it gladly. And that's the difference.
I think you do resent the intrusion of your sd in your life. I wonder if it's related to
But in my very black, most private moments I do wonder whether he just wants to recreate the family he lost when his ex walked out on him and that as long as I was kind to DSD and willing to slot into his and her lives with minimum disruption to them both, I could've been anyone really.
I don't know your dh, but I do know a man who got married very quickly after his wife died, simply to have a woman to mother his kids, so I know this does happen.
In your shoes, if I felt that was the case, I think I'd be just as pissed off as you sound.
I dunno - you sound resentful and he sounds stubborn and, if I'm totally honest, not all that considerate of you. Kick him up the arse hard, because when he starts being a better partner, I think it will all fall into place.
Good luck x
