You have no options, if he doesn't love you it's not a relationship. It's two people who live with one another, you will not be fulfilled. You'll die away slowly without love, just like plants need water. You perceive that there is a choice, but truly there is not. Councelling, doctors, talking. If he wants to do any of those things, then it would be your call to assent to try, but if he doesn't want those. GTFO!
