When he is nervous or secretive around you. He doesn't really want to go anywhere much with you! If he acts this way, don't judge him right away... Ask him, (make him swear on the Bible to tell the truth) :) just ask him nicely, don't force it out of him, just slowly slowly get it out of him! If he asks u on a date the next time, say u don't want to go, then he might say why not? Then tell him that u think he's keeping a secret, and that u want to know this secret! Hope this helps!
