Your wife went to the reception alone, but she definitely wouldn't be leaving alone.
This is based on an actual event from when we in our 50's. My wife was between boyfriends and had not been with another man in almost 2 years. During that time we had sex with each other about once or twice a week. However, when she got a new boyfriend her sexual appetite grew enormously and she had sex with him almost daily. He worked out of his home and she would often go to his house after I left for work. I remember this one time in particular that I came home from work and my wife told me she was going to his house again because she has super horny and wanted to have sex with him again. It is amazing to see the affect that a new lover had on my wife.
If you don't let her, you're going to lose her.
Even if I’m jealous, I want her to keep seeing him as much as she wants
