Girl hitting on my husband infront of me

So my husband and I were at a bar tonight and we were sitting in a table alone. I was drinking a blue Hawaiian and he was having a beer. So I got up to go to the restroom and when I come back, I see this girl talking to my husband. Let me tell you that I am not the jealous type, so I get to the table and before I get the chance to introduce myself, my husband buds in and says "this is Adalynn, my wife" she extends her hand for a handshake and she says "I was just asking him what you were drinking since it looked good". I continued to tell her it was a blue Hawaiian and she said ohh ok thanks, she shook my hand again and then his hand and while she's shaking my husbands hand, he begins turning red.  And I'm talking about tomato red. The girl walks away and my husband hands me a piece of paper that the fkn slut gave to him while they shook hands. The paper had her name and number and said call me when you get rid of her. Omg I was in shock! The audacity of her to come up to him while he's with his wife! Some people have absolutely no respect. I was pissed,, after she left he told me that before I got to the table that hoebag was inviting him to an after party after he dropped me off. i could not believe it! That bitch is lucky I never found her again after that cuz all hell would have broke loose. Has anyone ever encountered these type of women?? I am still in shock! I thought these type of things only happen in movies. 😡😤
