****Please keep this family friendly.**** No cuss words or innapropriate content.***** Ok about a year and a half ago. My sister in law had a friend coming over to our house alot. This friend, I will call "R", started making advances at my husband. Writting love letters. Then he started to get caught up in it and write them back. Well I confronted them both and it stopped, and did not go any further than letters. Well now my SIL is getting married. She has this "R" person as one of her bridesmaids. I have no idea why? Well I dont want to have any thing to do with "R", so I have decided not to go to the wedding? So am I in the Wrong Or the Right. It is a bit of a sticky situation here. My SIL says it is immature that I dont go because "R" is there. Well to me "R" is a toxic person to me. She tries to get any married man. I dont want to be around it or her at all. Or her other not so nice friends. I dont usually ask advice like this online. But I thought it wouldnt hurt.. My SIL and her family think it is stupid that I wont go. My family thinks I have every right not to go if this "R" person is there. What do you think?? ETA.. This "R" person just caused a couple to get divorced. Now since she broke a couple up. She should be on her next home wrecking adventure. She always moves on once she gets the couple to break up.
