I Have Something to Say

So I have a question. And it's for girls and ladies or simply females to answer. I would please want you to be sincere or just honest please. Simply tell me what you would do in the situation i'm about to describe. If you had a boyfriend, and you had a friend you talk to, who does somethings for you, though,small things, makes you laugh, though not perfect in been handsome or super cool. And one day, he tells you he likes you a lot via text. What would be your reaction? Or what would you tell him? He knows you have a boyfriend. Please let answer it based on what you would do in that situation. And be honest please.
