Been with dp 5 years and due to get married next year. I have a ds9 from previous relationship. They get on well, ds is very relaxed and happy to be looked after by dp. They play PlayStation together and that sort of thing. Dp is always kind and generous with him. He spent loads of money at Christmas for him. All good.
However I know for a fact that dp doesn't really enjoy or voluntarily want to do any 'family stuff'. Days out to predominantly kid places like farm parks or soft play (when ds was younger) he just doesn't enjoy. He will go and put a smile on but I know it's not his thing. I suggested a butlins holidays once and he said it was his idea of hell. Any school assemblies, plays and so on he wasn't fussed about. And during lockdown I've single handedly done all of the schooling (which is fair enough I wouldn't expect any different). If I suggest a family board game he will do it but again, I just get the impression that he'd rather be doing something else.
Having never had kids of his own I guess it's totally his prerogative to have his own preferences on how to spend his time. As a stepparent I never know how much involvement is reasonable. As we are going to be married and be a family of sorts I wondered if I'm BU to expect a bit more enthusiasm or if this is all totally reasonable from his perspective. Ds is getting older now so we don't do all the really young painful kid stuff now anyway but even so, I just feel a bit sad that he's not into the family stuff.
