Killer break-up line #1: "I don't think this is working out."

Let's start this "Killer break-up lines" series with: "I don't think this is working out".

When someone says, "I don't think this is working out", it's possible that the other person is thinking, "but I think this is working out."

If you're like any other person, when you hear that something is not working out, your inclination is...let's say it out loud...to work it out. Doesn't that seem logical? It's surely logical to me.

So you'll try to argue in favor of the relationship. You'll highlight the good times and state the strengths of your relationship. Which may or may not work.

It's a killer line because: It gives the soon-to-be-dumped a bit of hope that things can be worked out. Especially if the STBD (soon-to-be-dumped) is the sort who takes to challenges like a duck to water. A relationship stops working out when one gives up on it. As I've said before (and I'll say it again), it takes two to make or break a relationship. In this case, it's not working out because one of them decided enough was enough.

"B-b-b-but maybe we didn't try hard enough!"

No can do. When someone's decided to go, they're out the door. It doesn't matter how hard you try. In this case, it's really them, not you.
