Input: Really quick back story: My dad walked out when I was 7. Cheated on my mum with a woman who he eventually married (I wasn't invited). He only saw my sister and I around birthdays and Christmas and I eventually stopped seeing him for years.

When my sister got married last year she invited my dad because she still keeps in touch with him. I was planning to ignore him but his mrs cornered me and my fiance making small talk and eventually inviting themselves to our town to catch up.

We have all now met up for 2 fairly awkward meals. Now that I'm preparing for my own wedding I feel like I ought to involve them to some degree. Like not inviting them to any part of my wedding is an obvious snub.

If we hadn't met recently he wouldn't even know I was getting married. I don't think I'll invite him to the main day but I'm thinking evening just out of politeness. Am I an arsehole if I just snub him and don't bother inviting him at all?
