I looked back during doggy-style sex and realized he was smiling like Buddy the Elf. Not sexy. Repulsive.

Aftermath: I got drunk and called him on speakerphone with friends and told him the smiling-boning creeped me the F out.

He chased me down the freeway for a half an hour because I was going home for the weekend and couldn’t go to the beach with him. He also called me a “c**t whore b***h” and threatened to rear-end my car.

Aftermath: I had ended our 8-month-long relationship previously, but I was giving him a second chance. Needless to say, he lost that chance.

On the day of our departure for a weekend trip, my boyfriend of a few months showed up over an hour late to pick me up, then proceeded to throw a fit over why he was late. It scared me a little. Apparently, he was really late due to stopping for a burger.

—Bethany

Aftermath: We went on the trip, although I seriously thought about ending it right then and there. On top of this, he got ketchup all over my blouse when he finally hugged me and apologized for his outburst. The relationship lasted another few months until he proposed and I said, “No.”

I found out his ex-wife, who he said was his ex-girlfriend, was actually his stepsister!

—Kristin

Aftermath: He said their parents divorced before anything happened! What a crock! That is nasty! And of course I was checked for every STD you can get checked for. I also pawned his cheap-ass ring.

My parents were not happy about him not being Jewish, so they cut me off and I had to pay my college tuition myself. While I was trying to figure out my work schedule between my two jobs, he accused me of being money hungry for wanting to work so much.

—Marla

Aftermath: A few months later I broke up with him. I was working two jobs; he was playing Playstation 3 all day.
