Is my fiancées flirting innocent?

First things first.

A fiancé is a man.

A fiancée is a woman.

It's a French word, and French grammar.

Just like a masseur is a man and a masseuse is a woman. We have English words like that too: actor/actress.

As far as your question, no. It's not innocent. If you contacted him on fb, as an interested woman, he would agree to meet you, and probably would.

I've never cheated on my wife but she also knows I'm a huge flirt. I work with younger girls all the time and I flurry with each one. I'll go into a random store and flirt with the cashier or a waitress. But that's all it is my wife knows that when it comes down to it I won't do anything with anyone but her. Flirting is harmless as long as it doesn't go anywhere. But that's just one man's opinion. Good luck darling and stay beautiful.

If he cheated with her that's messed up. Ask him. If he lies you'll never know...unless he looks down and to the left. Otherwise tell him "don't get yourself F'd up ok?" And move on with your life.

If all he is doing to chatting online then yes you are over reacting.

I do that to I just like to make people feel good (I do what your bf does) he is not cheating
