How to Feel?

My wife becoming a Hotwife has been a fantasy of mine for my whole adult life. I told my beautiful faithful wife of 10 years about this kink around two years ago. At that time, she said that she was not ready, but has gradually changed her behaviors. It’s all kind of accelerated recently. She now brings it up more frequently than I do. She dresses very slutty, and demand my cock and my inability to please her in bed. She has told me that I am with her. She just wants me to come quickly and not to bother to try to make her orgasm. Skipping ahead to where I am at with her. We have had a young very fit contractor working on our master bath for going on a month. She frequently talks to him when I am not around, including having drinks with him at the end of his workday. Additionally, he’s come up in our sex talk when we fantasize together. Yesterday he was at the house working all day and we were home because it is the weekend. While I was out doing yardwork. She took off her bra and went up to chat with him as he worked, and she shipped wine. I came in and realized what was going on, tried to eavesdrop. I also realized that I had gotten hard and was masturbating to the thought of her upstairs with him, she has large breasts and her nipples are always hard so it is very obvious and a statement when she is not wearing a bra with a tight sheer top. She came down for a refill and realized I was inside and her face was flush. We didn’t talk much, but I grabbed her and we made out and it was hot. She was quite breathless. She went back upstairs and I got in the shower and edged while she was up there with him for about a hour. I’m sure they did not fuck but I am not sure that they didn’t make out or anything else. After he left, we made out and she let me rub her pussy over her underwear and I could tell that was she was extremely damp. I told her that I was extremely turned on by the whole situation and she said good, accept it. We had a family engagement well into the evening and I was not able to fuck her at that time. Then late last night she said that she wasn’t feeling well enough to have sex with me and was sorry because she knew that I was frustrated. Now today, Sunday morning one of the first things out of her mouth is a joke about fucking the contractor. Please couples who have been here, or Bulls on the other side: am I imagining something or are we on the edge of my Wife moving my fantasy into a reality? sorry if this is a boring post, but I am just really looking for some insights and advice. I don’t know if I am imagining things. I am also a mix of real world, jealous, anxious, and extremely horny.
