I've never loved anyone other than my current SO.
Introduce them to your current SO.
Tell the person that a CHANCE with you will require lots of public fawning, and lots of romantic gifts and gestures.
Same as above except you get them naked in a public place and leave them there.
Take them back with an open heart and live happily ever after.
Take them back and then cheat on them openly and dump them very publicly.
Hook them up with a really nice person.
Hook them up with the nastiest person you can find.
