How do you tell a shyish guy you like him?

Answer 1

The same way you text anyone else. This "shy guy" is still a human being.

Instead of being blunt and upfront, realise that it might take a little extra effort to coax him out of his shell.

Instead of "Hey, let's go to the park", try "hey, can I come and see you? And later if you like we can go to the park".

Answer 2

Assuming you have his phone number, just say Hi. It's the most simple thing to do. Chances are he will text you back, then you can go on from there.

Answer 3

Walk over to him and say i like you because.... and say what you wanna say

as easy as that
