We've been texting for a little over a year and i met him once about 2 weeks ago how do i know if he likes me or not?

how often do you text each other?

If he texts you in the morning, and/or at night before he goes to bed, and if you guys text, say jokes, send smiley faces, and if he calls you nicknames, or calls you "silly" if he thinks you're funny (which is something good), then you should know that you're always on his mind and he likes you! :)
