Bit of background: I left my ex after emotional, physical and financial abuse - he walked out on us many times and kept coming back and eventually, I said enough is enough. I am the main carer and do literally everything for them (school runs, hospital appointments, sick days, holidays, school events etc. all life admin). He sees them two evenings a week and a few days here and there in the holidays.
We’ve always tried to keep things fairly friendly for the kids. We used to do birthdays together and he’d come over at Christmas so the kids could have both parents there. Since his new girlfriend came on the scene, I’ve been told this will no longer happen - the children will do alternate Christmases with each parent instead - not that this will be happening as his accommodation is completely unsuitable (1 bed flat on heavily polluted busy road) and he does not even have a bed for them and has never made any effort to improve his situation for the children.
He's just spent the week away with his girlfriend and I've said nothing despite me never getting any significant amount of time away. The children and I had a lovely day today so I photo dumped some pictures to him and my mum at the same time. Amongst about 13 photos, there was one with me and the kids, and another one the kids had taken of me holding an old oil lamp at a museum (not a glamorous photo). I got a message straight back from him saying:
'Do not send photos of yourself again as it causes a lot of upset to GF'
For context - I have a partner too, and he goes on holiday with his ex and the kids. I personally don't have any issues with it - I fully trust him and understand why they do it. Most of the time, he's calling me a bit fed up tbh, but he does it because his children are used to family holidays and it makes them happy. Perhaps i'm in the minority here but I don't really get jealous of exes and never have.
I feel a bit taken aback. I send these photos for the children - they often ask to send this to daddy etc, not to get at him or her. Should I be worried about this level of jealousy from his partner? Is it unreasonable to say I shouldn’t appear in the photos occasionally? I'm a little confused as I have never had this problem and perhaps I am the one that is unusual about being cool with everything.
