I am loving the young boy whom I have kept in touch for more than
two years.
I thank him for his company and consideration for me.
What I am thinking to try the next step is to let him go.
I don't mean to ruin his life or give him no hope for future.
And what is the most important, he doesn't love me.
So..
Do you happen to know what to do to let him go?

He doesn't love you.So tell him your thoughts and see how it goes.It's not like he would get hurt or something.

Here I was reading your post and thinking of waysto give you some helpful advice, until..I read "he doesn't love me.", I mean...You both are on the same page, it seems..

I think I might've guessed the whole story lolIn most circumstances it's completely normal that people come and go in a mutual relationship (if you know what that means), there's no need to overthink, just do it
