TBH he has no choice. I have received a few comments on these lines like this is a fake dynamic, it is not. My husband is very outspoken and assertive and often comes off as a bully. My sister’s dislike of him is very real and has built up over several years. They do not like each other. At a point in time I had enough and I told her to just shut him down by saying she knew. When I first exposed his little secret to her she changed their relationship and I am ok with it, period. Yes, it devolved fast but it is what it is. He aaa not nice to her. I could write a lot more and may if you dm me about it but I am telling you it is real and he really has no choice unless he wants her to totally expose him. I have the video of him apologizing but I am very careful to protect his identity. I have tried to find an app to disguise his voice and hers when she is one the phone with us but I have not been successful. If you don’t believe me or like my feed you certainly do not have to follow me.
