the.com/dalliance

A fling with commitment issues even the fling didn't ask for.

means A brief, playful romantic or flirtatious involvement, or more broadly, time spent idly toying with something instead of taking it seriously.

from From the Middle English verb 'dallien,' meaning to chat idly or flirt, whose own origin is murky — possibly related to Old French 'dalier,' to amuse oneself. By the 1300s it was already doing double duty for both idle talk and romantic trifling, which tells you people have been commitment-phobic about this word for a very long time.
