You have to make a tough choice, and it depends on your inner strength. You have to be honest with yourself.

You'll be surrounded by all kind of good looking guys. The temptation is there. Many good people with strong morality fail to resist. It requires trust, and at times blind faith.

It's your choice. However, you indicated you wanted to go on dates, which is a sign of you want to enjoy your youth and explore. Don't hurt the guy if you really like him. I think the guy is starting to emotionally brace himself, just something you should consider.
