Pretty girl at work

I am married man and I have met a girl at my workplace around about 6 months ago. I am in my early 30s shes in her early 20s. I dont remember exactly how we started talking but we get along very well. I am the type that tells opinions how I see them even if its an unpopular one. She seems to find that funny for some reason and we laugh a lot around eachother and there's abit of flirting that we do.

We work for a logistics company where I am a driver and she's a loader. I often have to sit and wait for my trailer to be loaded and I will go in the trailer shes loading to help her and hangout which is quite unusual for a driver. My boss randomly sat me down and explained infidelity cost him his marriage. He looks at me sometimes when I'm talking to her and shakes his head before walking off. So I believe people are definitely talking about it at work.

Just about a week ago she said to me during a conversation about liquor that we should hang out outside of work sometime. I didnt say anything and then she said "just dont let your wife know" and gave me a grin. I didnt respond and gave her a look like "thats inappropriate". And I go out of my way to pretend like I'm not craving her when I am. And when she said that I honestly wanted to just grab her by the back of her neck and fuck her brains out right there.

The energy is so strong if we hung out anywhere we would undoubtedly have sex right away. To be honest I have never even wanted to have sex with someone so badly in my entire life. I also feel that if I am going to do it it needs to be soon because she will not remain on the "market" for long. Shes far too attractive and fun to be around.

I have never been caught sleeping with another girl by my wife. However I have caught her one time doing just that with a man years ago. She has once found messages when she randomly hacked my facebook and saw messages with a girl I knew from highschool and she deleted it and blocked the girl and just told me not to talk to her anymore. I believe I've been a pretty good husband and I believe if I were to get caught by my wife it would not ruin the marriage. I think that she would get over it and also she was guilty of infidelity herself years prior.

So I don't see this as being something that will destroy my marriage completely. I'm pretty conflicted right now on what to do and I am trying to decide if I am going to fuck her and if not I have to stop talking to her because it's just going to suck to have to feel all that energy and not get to. Im not going to torture myself.
