So I'm looking for some advice here. Long story short, my dad is bipolar and extremely unpredictable. Hes frequently emotionally abusive and hurtful, especially around big days or important events. I originally invited him to my wedding and even bought him a plane ticket since he's never financially stable and couldn't afford to fly to Hawaii on his own. Recently I posted on FB that I was sad my late mother wasn't able to go dress shopping with me, and this set him off. For days now he's been texting me long rants about how I have no right to miss her when I didn't try harder to have a relationship wth her before she died (she was an alcoholic) and how saying I wished she was there was a slap in the face to him. I tried explaining how hurt the things he said made me feel and his response was that maybe he shouldn't come to the wedding if I can't "handle the truth". Honestly I don't even know if I want him there. Can I tell him maybe he's right and he shouldn't come or is that horrible?
