<human>: Hello people,
I have been married to my wife for almost 3 years now and we have a beautiful baby girl together. She is stuck at home almost 24/7 because we only have one car right now. She never has any real desire to go out with friends though because of our parental obligations and the distance between our friends and us. She never really even wants to go out to a movie with me because of the cost and the nearest theater is over 45 minutes away. Aside from that stuff we have a great relationship and love each other with all of our hearts, truly. 

Right now I am away on a business trip and I noticed one of her ex's posted on a post of hers on FB. Now this ex of hers was actually a friend of mine in a past life, until he went off on me and my wife when we got together 3 years after they ended their 6 month (long distance) relationship. 

Anyway, I have told my wife in the past that I would prefer she not talk to her ex. She told me she would not ask me to do that, so I dropped it. I am not one to hold my tongue though and tonight I let her know how her talking to him was disrespectful to me as he husband. She got upset and said we should be past the jealousy in our marriage. I told her I am not jealous, but a guy that went off on me and erased me from his life, and later on apologized to her was not someone I am okay with her speaking to. 

I told her I stopped talking to my best friends sister just because she told me she didn't like me talking to her. My friends sister liked me at one time. 

This ex of hers also told me before her and I got together that he still loved her.

<bot>: Anyway, long ass story short. Is it okay for me to ask my wife to remove an ex of hers from her facebook and her life?
