Input: I am a married woman who was happily married up until a few days ago.  Recently my husband started talking about a new girl at work.  I thought, fine, I trust him, and he has other female friends.  

Soon I noticed the way he talked about her was different.  He seemed really giddy, almost like when we were dating.  It bothered me a bit, partly because she is 19 and I am 36, but once again, I trusted him, so I left it alone.  

Occasionally when he was texting her I would ask what they were talking about, and he gave me vague answers.  

One day I came home and found him talking on the phone with her.  This bothered me.  When he got off the phone I told him how much it bothered me.  I asked to see the messages between the two of them.   He said that they were private.  

He mentioned that the two of them had played a game where they guessed secrets about each other, and he gave his word not to show it to anyone.  I told him I felt this was too intimate of a conversation for "friends" to be having.  

He mentioned that she really didn't want her boyfriend to know they were talking.  Red flags went off in my mind.  I told him he needed to stop talking to her.  He refused, saying he didn't want to lose his friend.  

Eventually I decided to let the boyfriend know that they were talking and sharing secrets.   I figured I would want to know if I were him.  He said she had cheated on him multiple times before, and when he asked her about it she denied everything.   

After all of that, they broke up.  She told my husband to stop talking to her, therefore ending their friendship, and my husband and I are in a weird space now.  Am I the asshole for ruining three relationships?
