We have tried writing similar letters and cc'd the whole family because there was lying and manipulation of facts by SIL. MIL flew into a rage and cussed out my husband, SILs husband told us we were liars, and FIL told us that we are "tearing the family apart" (all because we want them to take responsibility for their behavior and we are putting up boundaries to protect ourselves). There was an overall census of moving on, but then no actions to back up the words. That is why we decided that we can't keep making any more efforts until there is a sincere effort on their part (but the trust has been broken many times over, and I don't think I could ever be close to them again). I don't ever want to be in the same room with them ever again! I'm just so tired with this situation...at this point, I just want some validation from my DH about the way we have been treated and for him to stand up to his family. I want to heal from this psychological trauma and get over the hurt and the pain and just move on and have some semblance of normalcy. I am so tired of dysfunction in my relationships - how do people build healthy families that love and respect and appreciate each other unconditionally?
