La La Landed 

When a couple breaks up because it is "right person, wrong time", with the expectation of getting back together a year or more later, but when they meet again one of them has moved on.

yo, my homie Ryan got la la landed as fuck. Casey even said she'd be willing to try again after her senior year was over.

LaLaLanded 

When you have to break up with someone due to personal goals and or distance. Typically happens to creatives. It is a reference to the film La La Land.

I’m trying not to date anyone because I don’t want to get LaLaLanded when I move to New York.
