So future husband has this "friend" I use this term loosely as I've seen this guy and his wife once in the last year. Also my FH was supposed to be a groomsman in their wedding only to end up NOT EVEN INVITED! so on to my problem. He is insistent that they be invited to the wedding. Which typically I wouldn't object to inviting an estranged friend, I have a few myself, but in this particular case the bad friend guest also comes with a host of baggage. There will almost certainly be a argument or some case of drama involving him. My FH sister-in-law and him have already had multiple altercations. He has a horrible attitude which only gets worse with alcohol. Considering we are having open bar this will most definitely become and issue. PLEASE HELP!! I need advice on talking my FH out of this decision, or just how to deal with this character!
