I’m sure most of us have been there at one point or another. Your relationship with your significant other couldn’t be better—except for one thing—“The EX” or “The ‘best’ friend of the opposite (or same) sex. It’s that one person that your lover has been friends with since even before you got together—and its that same person that your lover will fight and argue with you about; saying they are just friends.

And for the most part that is true. But…

You know there is a history between them. And when your significant other claims he or she is just friends with the other person—but refuses to introduce you to him or her. Or when he or she says there’s nothing between them, but gets defensive about you questioning why they need to talk, email, keep in touch on MySpace, send each other notes on Netflix and forums—your blood turns cold because you know that he or she is refusing to see (or perhaps sees but doesn’t care) that he or she is having an emotional affair.

That’s why I hate Lynn.

He refuses to introduce us because her poor little nerves might not be able to take it or because she simply doesn’t want to. He refuses to stop talking to her because she is “the only other person in the world I can really talk to.” Yet I am not good enough to be acquainted with this person.

She doesn’t ask him about me. She won’t meet me. Sending a red flag that there’s still something there on her side.

And that he takes to her defense—it makes me wonder if the feeling isn’t mutual. When I ask if she has a boyfriend, he can’t answer the question. He hasn’t asked—and she doesn’t say.

No words can describe how much their relationship makes my blood boil; my fingers tremble even as I type:

I hate Lynn.
