I'm scheduled to have dinner tomorrow (Tuesday) night with an old friend ("John") from high school. He's a commercial airline pilot and is only in town a few days every few months. John texted me tonight to let me know that he's bringing another old mutual friend with him to dinner. John didn't ask if I wanted to see this person. I do NOT want to see him. I am friends with his soon-to-be-ex-wife as well and she filed for divorce from him in November due to his mental and physical abuse of both her and their kids, and the fact that he's a manipulative,controlling, misogynistic, selfish asshole. I'm almost certain John doesn't know the truth about the divorce and that's why he thinks it'll be good to hang out 'just like old times'. I've also been providing the STBXW with screenshots of her husband's Facebook rants trashing her on his page to anyone who will listen so she can give them to her attorney to use in the court case. I don't want to lose my ability to do that, and I don't have a friendship to protect anymore with the jackass. (I'm laying real low on FB so I don't give him a piece of my mind, he's just on hidden status unless I go to his page directly.) After the divorce is final I will probably remove him from my life completely.
So... if you were me, how would you get out of this dinner gracefully under the circumstances? I'll be really bummed that I can't see John, but I swear I won't be able to keep myself from beating the holy living snot out of the other guy. And I don't want to raise enough questions that I get found out. I truly don't have anything else going on that night to claim. And John wants me to pick the restaurant...
