Hello
First post under this name, have posted before. Hopefully this isn't too contentious.
My DM and DF split very acrimoniously when I was a young teen. He left her for OW. She took it really really badly and me and DB were her sounding board for how awful he was, how awful OW was, how she'd been suicidal etc. It was pretty grim and we were put under huge pressure to be 'on her side' and tell DF we didn't want to see him, to shun OW, to make demands on her behalf when we went to see him.
In the end I developed a ED, ended up in hospital and when I came out went to live with DF and DSM. This was, according to DM, a horrible betrayal and she said a lot of awful things to me which our relationship has never recovered from. Looking back, I suspect her relationship with DF was abusive - she used threats to control him, used to break his things if he disobeyed, stuff like that.
It's now many years later and my relationship with DM has remained fragile. I've just had my first DC and my lovely OH and I want to have a proper christening. However, I'm very certain that DM is about to kick off about this. She has refused to be in the same place as DF and DSM for the past 20 years, and has frequently made dramatic threats about what she'd do if she did see them. She will go ballistic if she's not invited, but I can't bear the thought of DD's christening being some bloody awful Eastenders/Jeremy Kyle showdown. I also don't want to invite her and not DSM and DF as they are the people who actually raised me, and have been there for me, and I have a very good relationship with.
Help! Has anyone dealt with a situation like this before? Does anyone have any advice?
