I am in a situation with my SIL where she has lied about me to her mother (my MIL) She told my MIL that ai had done something to her behind her back, which I have not. That lie resulted in MIL turning her back on me and my children (her grandchildren) It didn’t take much which makes me think many mire lies have been said over the years! My DC and SIL’s DC are of similar age and were very close. Due to SIL’s lying I have been trying to keep a distance but still maintain some sort of relationship for the children. I have asked SIL a few times if her DC would like to come and play, to which there is always an excuse (my gut instinct is that she is also lying to her children about me). She has now said that my DC can go over to their place but my nervous system is frozen, I do not want to stop my DC having a relationship with their cousins but at the same time dont wish for my children to be in the company of someone who has lied about me and who is the reason they no longer have a loving grandmother who wants anything to do with them. The lie is so ridiculous even if it were trie it woukd be no reason to cut us off which is making me think there have been far more other lies said. I want to word this in a way to SIL that I would love for my DC to spend time with them, but whilst this lie is still being told and jo one is being honest about it I am not comfortable for it to happen.
