Sorry to whine so early on in my BnB life but, my fiance's sister is 17, she has been with her current bf for 8 months and she was pregnant by him after 2 months,we get on well with him and he treats her properly. When my MIL asked me what I was going to call the little caterpillar in my belly, I told her, and I guess she shared it with the rest of the family in passing conversation. Thought nothing more of it, most of the time we get on great and have done since I met my fiance 6 years ago Caterpillar's middle name is a variation of my mums name, as an honor to her as she recently passed away. A few days later on Facebook, his sister posts a status saying that she has decided to call her child not just the first, but the middle and last of the names I had chosen. Last name isn't a problem as I guess it's her surname anyway, but then she put a comment to one of her friends saying that her "brother's stupid girlfriend was trying to steal them from her" and that she "wasn't going to use the middle name after all because it was crap and she wasn't speaking to me until I changed Caterpillar's first name to something else." And true to her word she has totally ignored me (and made her bf ignore me) since, it's making an atmosphere for everyone and making my fiance sad . Sister's boyfriend told her that she was being childish and that she should just choose a different name but she has convinced herself to the highest degree that I stole the name from her. It's just a name, but it's the name I want to use! Naturally as her mother, my MIL has taken the sisters side and has told my fiance to make me change the name and now the mum and the sister are always making snide remarks about me saying that I think I can always get my own way just because "she's spoilt and daddy brought her a nice car" and other silly comments about possessions that have absolutely no relevance. They have very little money and are in serious debt, I brought the sister everything she wants and needs for her baby and her nursery to help her out so she won't worry. I think that they thought I was looking down my nose at them and laughing but I was only trying to help as I understood how she felt because we are both soon to be first timers and it now seems like the mum is using this name silliness as an excuse to hate-fuel towards me as an outlet for her own resentment at being unable to provide the things for the sister's baby and after 6 years of a great relationship with them all, I feel like I have been pushed out of the family and nobody wants me. I'm only 22 and very soft and I feel so depressed as MIL is the closest thing I had to a mum since mine passed away. This isn't healthy for caterpillar at all, it's a long complicated and probably a more than one solution story but how can I fix it?
