My "D"M has form.
Several years ago I went for counselling (marriage very unsteady, never recovered, now nearly divorced). Psychotherapist asked what relationship was like with my mum. I said she reels me in, gets me close then spits me out with a venomous and rather spiteful conversation / action / reaction (massive drama queen, amazing in a crisis, although will refer to any past support she has given as a "you wouldn't have got through that without ME"), so in general I keep my distance. We have a fairly good text relationship but spending time together doesn't work.
At the time, I discussed the conversation with my mother. She said yep, that's how it is, she acknowledged that it's the same way her mother treated her, that she hated it, however she told me she wasn't ever going to change. She hasn't. (For reference I have two sisters who she gets on with very well.)
On the other hand, I have an amazing relationship with my dad. In the main he and I see each other separate to my mother. I lived abroad for years and he would visit every six weeks. I adore him and respect him hugely. We have very matter of fact conversations, talk "shop", politics, share good reads, and he is an intelligent and supportive loving dad.
My mum is jealous of this and recently manifested a massive argument between us (she has done this before). When I said "I do not want to have this conversation now" (it was late evening), she threatened to hit me (I'm in my 30's). In order to defend my response to her argument, I asked my dad to confirm a conversation that he and I had had about four weeks prior.
To my utter dismay, he denied it.
He hasn't spoken to me since - I am distraught that my mother has managed to break the relationship between me and my dad. She will be rubbing her hands together with glee - see, when she was younger she "wasn't allowed to have a relationship" with her father as apparently her mother never let them.
AIBU to go NC with "D"M and try and salvage my relationship with my DF? I don't even know where or how to start the conversation with him. I just know that she hates me, and this won't ever change. She's even got my sisters rallying around her and defending her behaviour! I'm sick of the bloody drama. I'm going through a shit divorce, trying to manage my young DCs and juggle childcare and a job. I just don't need this.
So many times in the past my dad has said "just ignore her". I have wondered if in fact he denied his and my conversation because he just can't be bothered with the fall out. If he was 20 years younger I wouldn't blame him for leaving. (This entire last paragraph is pure speculation).
Sorry for the long rant. Just unsure what to do.
