will it pass?

I am married. These days I had a crush on a very young guy, he is my coworker, I told him asking for some physical relationship, but he doesn't want to do, I told him I feel very sad by his rejection and beg him for just holding hands for some time, he agrees but he said after that there is no mentioning of this anymore, he also mentioned that no matter what I tried, he won't have feeling for me. We talked a lot about this, he just wouldn't do it.

I am now very depressed, when this feeling will pass? we have to work together.
