Sometimes we feel a strong connection with someone without ever really understanding the reason. It's a shame that this unavailable man turned the connection into something sexual by kissing you. I don't know if all crushes just go away, but normally they do diminish over time. I feel that you value this connection and fear losing it. The problem with this is that by making it sexual, he has disrespected both you and his wife. You might always feel something for him, but it would be a lot easier for you in the long run if you could replace him in your heart with someone else, even for a short time. Caring about someone else can help break the invisible ties to him and weaken the bond. I wonder if simply naming this for what it is ... a connection and not necessarily love ... is the start of your becoming stronger and more able to move on. I wish there was an easy solution, but it takes time and for you to live your life to the fullest without him.
