Very recently, my grandmother and my grandfather got divorced. It's been a long time coming, and no one (including my grandmother) is surprised. He's actually her second husband; she was widowed before I was born. He's a nice man, but has a bit of a temper, and it wasn't until recently that I really started to notice he was being emotionally and verbally abusive to my grandmother (who is, as far as I'm concerned, the sweetest lady alive). Chalk that up to maturity, because my mother assures me this has been going on a looooong time. My issue is that now, I don't want him to be invited to the wedding. The divorce is civil, and there would be no fights or anything like that, but I know it would be awkward, and plus I'm very unhappy with him. My wedding is a year+ away, so I may feel differently by next spring when the invites go out, but as it stands right now, I don't ever want to speak to this man again. My grandmother's had a hard life, and lost her first husband to a very aggressive case of early onset Alzheimer's, and i don't think that a man that treats her with disrespect deserves anything nice in return. What should i do?
