We all have those friends. Every time you see them you ask about their sweetheart, only to discover you just put your foot in your mouth. They are no longer dating the person you met last month but now have someone new.

They’re called “serial daters.”

We’ll call them victims of dating ADD. They’ll say, “I really like Tim. He’s super exciting and really fun to be around.” A few weeks pass and the excitement has dwindled to pure predictability. Their eyes have since wandered over to Dave, the guy who made the awesome beer pyramid at the party last week. I’m sure it was quite remarkable. The serial dater is left saying, “Tim who?”

Perhaps they just love the opposite sex. They’re the outgoing types who always meet new people and get along with just about everyone. Blondes or brunettes, they like them all; they even throw a red head in the mix from time to time.

Maybe they’re just really decisive and picky. You like Pepsi? Well I’m a Coca-Cola girl so I’m not sure this is going to work.

They could just be the George Costanzas or Samantha Joneses of the world. The womanizers and manizers who don’t get emotionally attached, but are more sexually motivated. If you come across one and end up getting dumped a few weeks into it, don’t fret. It wasn’t you, it was them.

Essentially, everyone they date is a rebound. These people are never single. Their relationships may be short and sweet, but they practically overlap. There is always a prospect waiting in the wings before the pink slip has been handed to the former. Single is not an option for these folks.

How do you know if you’re a serial dater? Well, if you’ve ever blurted out your ex’s name when speaking to the current squeeze, you, my friend, might be a serial dater. If you’ve swapped names, maybe you were the one sent packing.

Mistaken identities are relationship killers. I hope this unexpected breakup didn’t leave you single for long. I’m sure you’ll rebound in record time, you pro.

Once you recognize the routine these friends encompass in dating, you’ll know better than to use specific names when inquiring about their love life.
