My parents are still together despite my dad's alcoholism and selfish behaviour. I have always disagreed with his lifestyle but have a civil relationship with him for the sake of my mother who I adore.
I only go back to my hometown 2 or 3 times a year but when I do he is always drunk or fails to turn up to meet me, out drinking instead. He disapproves of the fact I'm not getting married in my hometown and our strained relationship has broken down completely with him sending me abusive drunken texts calling me selfish for the location of the wedding. He hasn't had a nice word to say about the wedding from day one but I was willing to suck it up and tolerate him walking me down the aisle etc for the sake of the family but his recent insults, heavy drinking and not turning up when I'd driven down the country to see him have been the final straw and I don't want him to walk me down the aisle- he's not been any kind of father or been a feature in my life so why would the biggest day of my life be any different, especially given his recent behaviour. After months of no contact he text me to tell me he's invited 8 of his friends, who I don't know, to my wedding. When I told him there weren't enough room he replied that he wouldn't be coming at all if that was the case.
I now don't want to invite him at all because he is petulant, a drinker and doesn't support me or the wedding- I cannot trust him not to ruin the day but I know my mum is caught in the middle.
What do I do?
