The person who was part of the most significant or meaningful relationship that you used to be in, but aren't anymore. You can have more than one ex, but you can only have one significant ex.
The other day, I ran into that guy/girl I went out with for a little while and it was pretty akward. Glad it wasn't my significant ex at least!

He told you he wanted to marry you on the fourth date. He quit college and told you to relax when you said you were concerned about their future. You'll feel guilty thinking about guys who actually take their girlfriends out after he stops wanting to go places. Before you know it some girl says she's dating him. The ex boyfriend isn't serious about marriage and has tons of ex girlfriends that you never knew about. He'll disappear from your life.
