She actually asked him to sleep over to look after his girls a couple of days before our wedding this year! That is so cheeky!
She wanted to come on holiday with us, err, no. Oh my can you imagine?
It seems sometimes having kids with someone blurs the boundaries when they split up.
ExW has been so difficult and attacked for unfair reasons, whenever she's pissed off says DSS is nothing to do with me. My DPs ExW makes it quite clear that I am invisible. She does it by always texting DP, never acknowledging me, indeed even ignoring me outright in front of her step children. No wonder they are conflicted.
Sleepy and others - my DPs ExW was most 'intrusive' when we had a baby, I wonder if it was a reaction to not being able to 'corner the DP market' as it were?
Also, when me and DP did split up temporarily - I think ExW and DSCs may have had a bit of a reality check. DP didn't suddenly turn into someone who was exclusively 'theirs' again.
The DSCs couldn't just rock up and use the big TV, because DP didn't have a big TV anymore. ExW couldn't demand as much extra time, or extra lifts, or extra money. DP was trying to stretch himself and of course, now had to include me. And believe me, suddenly I found myself priority, for the first time in a while!
Claude I don't think it sounds unreasonable, and if you are having to parent, well then you have to be your sort of parent! Step Mums are not paid childminders, and even childminders will tend to have their own way of dealing with children too, not just a robot for the parents style. If the DSC has trouble adjusting it is the parents who should help them, by backing you up or not putting so much pressure on you in the first place.
