I don’t really get on that well with my sister in law , we tolerate each other for our children’s sakes but there is no love loss ... my husband doesn’t have much time for her either but again does his best to be nice when we’re all forced together. I’m pretty much left out of most female family get togethers and if my MIL does anything with me my SIL makes her feel guilty over it.
It’s my nieces birthday soon and we have been invited as a family to her chosen activity , our kids don’t get on great and mine don’t want to go ... would I be wrong to not go ?
