My DM and DF have been divorced since 2011. Other than seeing each other at my sibling's and my wedding - they have been NC since. They hate each other's guts. The divorce was long time coming as they had a bad relationship ever since I was a child.
3 years ago, my dad met this woman. Everything seemed great - they have same interests in history and politics, they frequently do day/weekend trips, go hiking and exploring new places, they both love eating out... seemed like a really great match. Occasionally, however, they'd get into a spat and it would always be very dramatic. She called me once or twice in a complete state, drunk, crying about my father not loving her, still being in love with my mum or the woman he briefly dated between divorcing my mum and meeting this woman. I expressed concern, but didn't press - just wanted my DF to know I'm there if he needs to talk.
They got married yesterday. It was a small registry wedding with just immediate family (my sibling, myself and the woman's son with partners) and 2 witnesses present with their spouses. It was a lovely day, everyone was happy, lots of laughter and all seemed perfect.
An hour ago I received another call from her, sobbing. My heart stopped - I thought my grandmother or my dad died (he has a heart condition). She proceeded to tell me that my DF called her by my mother's name and this is a 'proof that he never loved her and is cheating on her' with both my mum and that women he dated in between. 'I am like a daughter to her so how could I not tell her, how could I let her marry him'. I tried to calm her down and reassure her because if there is anything I am 100% sure about - that is that my dad is NOT cheating on her with my mum or that other woman. She wouldn't calm down so I asked to speak to him. He told me she is drunk, to forget this phone call and not answer her calls anymore. He apologized to me profusely and used some heavy words to qualify her behaviour.
This happened an hour ago and I am still very upset. I'm worried for him and his health and I am desperately sad that this is happening on the first day of his honeymoon. The thing is - they have planned a blessing ceremony this weekend and it was very important to my dad that my family attends. I can't imagine doing it now - even if they proceed with it.
Am I BU for being angry with her for calling me? I don't know if I can keep pretending stuff like this never happened and I don't know what to do.
