How wrong is it to fantasize about the HVAC technician?

Lately I had been feeling bad about myself.

I was laying in bed next to my partner and fantasizing about the HVAC technician. I felt like I was cheating on him, but there wasn’t a real person there. I considered talking to my partner about how I was feeling, but I didn’t want to hurt his feelings. I loved him to death, but there was something about the HVAC technician that caught my attention and I couldn’t break the bond. Three days later, the HVAC technician came back to the house to install the part he had ordered for the air conditioning unit. My partner was home that day, and I tried to act as normal as possible when he was talking to the HVAC technician. I couldn’t even stand to stay outside and see Bill talking to that man. I was jealous that he was the one who got to talk to the HVAC technician and I didn’t. After the HVAC technician left, Bill came into the house and sat down. He asked if I knew the guy had a crush on me? I could honestly say I had no clue. He told me the HVAC technician said he was going to ask me out when he came back. Although I was smiling on the outside, my insides were shaking. Had Bill not been there, I don’t know if I wouldn’t have considered going out on that date. I don’t know how Bill knew what I was thinking, but he told me it’s normal to fantasize about other people even if you are in a committed relationship. I realized how much I loved that man.
