Boy problem :( I've fallen in love in the worst way.. PLEASE HELP 10 points!?

Yes, you're doing the right thing by ignoring him. Guys typically want what they think they can't have, so you're increasing the mystique. If you're too accessible they won't be interested. He needs to come to you and explain why he started acting odd towards you. If he doesn't, then his issue must be bigger than his curiosity.
