Stop caring about how he feels and live life the way you want to.
Seriously, any sort of jealousy-inflicting strategy beyond that will turn out to be a bad idea or have repercussions you don't particularly want. So, ignore him, and go for something else you want in life. Either you'll arrest his attention or, more likely, find somebody better.

Trying to make someone jealous only works if they already care about you. If they aren't aware you exist or just generally care about what's going on with you, nothing you can do will make them jealous.
