My SiL has always been a bit of a mystery to me, she's very moody and can be immature but she can also be great with my kids too.
However, recently I have stopped speaking with her and whenever she asks to come visit I make an excuse and say I'm busy. This is because she was sat in my house, as a nursing student, telling me about how she was working with kids in a special school who were 'cabbages'. When I asked her not to call them that she said 'oh I don't say it at work' and I said 'just don't say it anywhere' and she fake laughed and changed the subject.
I don't have any family of my own, my only family is my in-laws due to being in care previously. I have a rubbish relationship with my MiL anyway and I don't know, I'm feeling isolated like I'm picking off family members to not get along with but I feel she's gone too far.
Would you let this go or not?
