Guys and girls, advice please, what do i do about the guy i like?

You could be bipolar and that was a coincidence your mind is making up, Or you could be fabricating things out of thin air about how the first guy likes you because it is often that way and you really don't know much about him. Then you may find you like the second guy more or not at all. It's okay to be indifferent in relationships, it's not always supposed to be on-off.
