I have an ex that I wish I could see again, even though I'm with someone. I feel like a horrible person.
That's understandable, just because you were once together and now you're not in a relationship doesn't mean that you can't still have some feelings for her left.

True, or like "ex-convict." Or "ex-military." Those are some ex-tra ex-amples for you.
Ex (relationship)
In social relationships, an ex (plural is exes) is someone with whom a person was once associated, in a relationship or marriage. As a prefix, "ex-" can refer to a variety of different relationships; for example, one might refer to a music group's "ex-guitarist", or someone's "ex-friend".

It was really great to see Willie in the halls of "Mode" again and back to all her scamming in her ultra-chic office. And I can't even begin to tell you how great it is
