This character is involved in a romantic relationship that doesn't work out and "gets dumped" by their partner.

A relationship breakup, often referred to simply as a breakup, is the termination of an intimate relationship by any means other than death. The act is commonly termed "dumping [someone]" in slang when it is initiated by one partner or "getting dumped by [someone]" for the partner on the receiving end.

Please refer to the "Engages in/Breakup" for characters that are the ones initiating the breakup.
