So I agreed to be best man for an old friend who clearly doesn't respect me. He ignores my calls but texts in a group chat 3 seconds later, and after I asked his wife how her holiday was in a long message showing loads of interest she didn't even reply. Had a tough year as I got divorced, so now in my life I will not be disrespected, how do I pull out? Do I just say the truth or do I make something up? Either way I don't want to do it because I've seen the guy once in a year and this was when I was going through the toughest time of my life.... divorce from an abusive ex wife.

Any advice?
