My SIL has been horrible for years. Caused massive drama over her wedding, wouldn't attend my sons christening because she didn't like the date and wouldn't allow my brother to be god father to my son. She has been overly dramatic for years and caused so much stress. It ended up with me not talking to my brother for 2 years because I couldn't take the stress of her dramas anymore. We have never done anything horrible to her. If anything bending over backwards for her for years. My mum let them live with her for years rent free and they show nothing but disrespect towards her and my dad. She likes getting attention by claiming to be picked on and being a victim. Anyway she is pregnant now and we have done everything not to upset her as she is easily upset, My mum organized a lovely meal and paid for her as a baby shower treat and invited a few female members of the family. She has now demanded that my brother be present at all times and will not spend the couple of hours with us on her own. My mum offered to collect her and drop her off but she is insisting brother be there. She is too ill apparently to not be with him but was just on a hen do a month ago and other nights out. It just feels like another slap in the face. I don't want to go to this baby shower now but mum is begging me to go as she doesn't want her to cause another drama. How to deal with this???? She is the biggest a**hole I have ever known.
