You can if you talk in general dont always message him all the time because then he will think that your are annoying but if you talk and you get closer things might work out if not you cant really force anyone to like you
I think this is coming from the Henry Ford quote, which is "Whether you think you can, or you think you can't--you're right."
This quote basically means that what you think you can do is all in your mind and how you perceive yourself. if you think you can do something, then you'll be able to do it. If you think you can't do something, then you won't be able to, because you have already given up in your mind.
Does that make sense?
