Someone who you never really verbally had the chance to break up with (probably due to lack to technology or secrecy) where distance and/or random event caused an unexpected split.
"My parents decided to move out of the country short and notice. I wanted to call and tell my girlfriend but the phone had already been disconnected. I never got the chance to officially break up with her and didn't really want to. So technically she's my unofficial ex. I found her on Facebook....she's now married with 3 kids."

Get the unofficial ex mug.When two people are dating, but not in a relationship. Even though they are not officially together both individuals are not looking to get with or date anyone else.
