Is It Normal To Call Your Crush Your Boyfriend?

Yes that's normal. Guys can always sense when you're attracted to to them, and they always feel the same way. He's deeply in love with you, but just hasn't admitted it to himself yet.

The more you introduce yourself to people as his girlfriend, the more you'll bring his desire out of his subconscious. Change your Facebook status to "in a relationship" with him, and write your name with his surname on everything.

If he still hasn't admitted to himself that you were made for each other, turn your room into a shrine dedicated to him. Secretly take hundreds of photographs of him and put them on your walls. Steal some of his underwear - guys think that's really hot. Also try leaving your dirty panties under his pillow. When you show him your shrine he will be moved to tears by the depth of your devotion, and will have no choice but to admit his undying love for you.
Don't be at all discouraged by a restraining order - it's just his way of testing the depth of your love.
