For context- my SIL has no children of her own. I’m close to her though have struggled a bit over the years with her being slightly blurry with boundaries, I’ve experienced her as intrusive at times (though in a well intentioned way). She lives in the same town as us and as my adult children who are all in their early 20s and who all live independently.
My SIL will ask my children around for supper without asking us. I know it’s silly but it makes me feel like she’s stealing them away from me, it makes me feel displaced/competitive… My own sisters, who similarly live in the same town and who have children of their own would be involved with mine but would only see them if we were all gathering together… the same with me and their adult children. I wouldn’t see them independently of my sisters…
I don’t know whether with my SIL she is just doing things a different way, different from how my family do things but not unreasonable… or whether there is something a bit odd about it…
AIBU to feel aggrieved??
