MIL coming to stay and i haven't spoken to her for 3 years - still speaks with DH but we live far away and so she hasn't visited for a long time since we fell out. Alot of background which I won't go into. My 5yo has ASD, diagnosed at 3. Pre diagnosis I had been visiting MIL when she told me that DD didn't have ASD and it was in my head, and she was just very naughty and we poorly parented and I was the problem. Since diagnosis she still doesn't accept it and says DD is just naughty and badly parented. I didnt want her to come out but DH is no contact with his dad and his family generally don't make any effort to keep in touch with him so I wanted him to have a nice time with his mum.
Should I just grey rock all weekend. Most interactions with her previously have been hostile (her side not me) usually after she's had a drink (which she probably does have a problem with IMO).
Any advice on how to handle? We will be spending time together so unavoidable. Do i wipe the slate clean, see how far we get without trying to get along?
