What do you do? You grow up.
You realize that what you're doing is not maintaining a relationship with someone you love, you're clinging to a fantasy with someone you lust after.
You can commit to a real relationship, and start putting that relationship first, realizing that there are things more important that yourself. Or you can move on with your life, realize that it's not going to work, and get over it.
And 1.6 years for a reaction like this? You sound like you're about 16. This is part of life. Time to put on your big boy panties and become a man.
