I have had a few occasions of my fiances SIL getting involved in our relationship. Things such as she has asked me why I do not post him on social media and said she thinks its strange; and just being generally interfering; I also checked my fiancés phone (one time, for good reason) and she was talking negatively about me, things such as “you will be free soon LOL” when I am about to leave for work after we had an argument, and him generally confiding in her when we had a huge argument one time recently.
Rather than give advice she was just agreeing with his view and being generally unhelpful. The confusing thing is she has asked me to be a bridesmaid…and is nice to my face. When I text her after I found the texts I pretty much told her to stay out of our relationship (I have had to tell her this twice already). Today she sends me a “joke” TikTok - Make Your Day saying "hahaha this is me and my sister we are crazy". I just don’t think this is funny and getting to the end of my tether. Fiance has said he has told her to stop talking about me, obviously she doesn’t pay attention to anything he says. He gets angry and defensive when I talk to him about it and says all women stress him out and he doesn’t want to be involved?
Should I just ignore it? I am 6 years older than her and its getting frustrating...
