Cannot give too much background as it would be outing. However, SIL is a 30+ year old woman but is very entitled, spoilt and has high expectations of her family members, especially my DH. We have lots of arguments about this and it creates a real issue in our marriage which is starting to really get me down. I feel a lot of resentment towards her now because of her expectations and the way her demands requests cause issues in my marriage.
She lacks awareness of boundaries and DH is not good at communicating these effectively to her, but when I do, she cries or makes a big fuss. Honestly, I try to have minimal contact but that only goes so far.
Any advice with how to deal with a SIL like this?
