My brother set me up with a friend of his and we went on a few dates. One day while at my job at an elementary school, I was in the teacher’s room flipping through pictures of local sex-offenders. There was my date in all his glory.

Aftermath: I never saw him again, and confronted my brother. He said he knew that the guy was a registered sex-offender, but didn’t think that it was a big deal. I have 3 kids.

After a few months of dating it seemed like all she wanted was a “F**k buddy.” I told her I wanted more than sex. She replied, “I know how much a guy loves me by how much he wants to have sex with me.”

Aftermath: I found out she was cheating. I haven’t seen her in a year.

I came home and my girlfriend was going at it with another guy in our bed with her 4-year-old daughter in the next room. She thought I was coming home later.

Aftermath: I moved out the next day. She later asked me to give her number to a friend.

I caught her in a cheap motel with a co-worker. Her mom was in another room with a friend of the co-worker.

Aftermath: Divorced

My husband and best friend walked into our apartment together. He informed me she was pregnant, it was his and I was out—she was in. Those were his exact words.

Aftermath: I took him for everything he had.
