A friend of mine recently called off her wedding. This did not come as a complete surprise as there had been many problems between my friend and her FI. A day after I heard the news I found out one of the driving forces behind the cancellation was that the bride had secretly been dating someone else during the whole wedding planning process. This includes all night contact via text during her couples shower. I also found out that it was her secret BF that drove her to her hometown for her "bachelorette" and she had planned to bring him out for the night (that was the night everything ended up being called off). I don't know if this is relevant but I believe her FI does not know about this 2nd man. I'm really turned off by her decisions but I also recognize that its her decision to make so I don't think its a good idea for me to voice my opinion on the matter to her. At the same time I don't want her to think I support her behavior. She also has a child with her FI so my heart really breaks for him in this situation. I wonder if it is time for this friendship to come to an end because I just don't know if I can support her through this. Other things have happened in the past to make me seriously rethink our friendship and I feel like this is it. I haven't talked to her personally since this all went down as I have no idea what to say. WWYD?
