Therapists, self-help gurus, and women's magazines may disagree with us, but we don't think deteriorating relationships are that hard to detect. We're firm believers that both parties are fully aware when a dating scenario isn't working. Yet, rather than serve the relationship a swift beheading, many allow their boyfriend/girlfriend status to die a slow, painful death.

As the Tao Te Ching wisely advises: "Know when it's time to stop. If you don't know, then stop when you are done." If you're having a hard time figuring out the "done" part, see our list below for a few telltale signs. If you check yes to even one, you may be as done as a Thanksgiving turkey -- unless you make a sincere effort to make your relationship last.

Remember when he first called on that dreary Tuesday? Suddenly your headache morphed into rainbows and glittery unicorns. It was the second best thing to a spiritual experience -- a head rush of magical endorphins, if you will. Now the phone rings and your face contorts into a grimace. You press "ignore."

Oh, and that specimen over there, the one in the blue shirt? Gorgeous. You suddenly feel the need to openly check out their body. Gape even. Sound familiar? If yes, then you're self-impaling, my friend. You're hoping to come across as grotesque so the other person can do your breakup dirty work for you.

Suddenly you have early morning meetings and a newfound dedication to a.m. workouts. There are late-night book clubs to attend, cleaning marathons (see #2), Netflix, and obsessive tweeting. You're also just super tired and feel kind of sick. In fact, you'd be fine if the romance didn't happen at all tonight. Or tomorrow. Or even next week.

You're 100 percent certain that dark-haired cutie who camps out at the copy machine does so because you get coffee at the same time. The sandwich maker at your favorite deli was checking you out, no? Let's just send a online message to that old coworker you've always liked. See what happens. Maybe they'll want to check out that movie this weekend. Just platonically, of course...
