I am 23, so mine might seem a little juvenile, but it was a horrible day nonetheless. The following is 100% true, and not exagerated in anyway.
In Fall '08 I was working on getting back together with a girl that I had dated on and off for ~3 years (Alicia). It was a terrible relationship looking back, but it was one of those where you just beat yourself into the ground trying to fix everything and not seeing the bigger picture. She broke up with me in the summer so I called up one of my high school GF and we had sex that night (Jamie). Being the asshole that I was, I completely dropped Jamie with and started to try to get back together with Alicia.
Jamie transferred to the school that both Alicia and I attended a month later. One day, after not talking to her for a month after the sex, Jamie sees me walking through a building on campus and gives me a go to hell look. Not thinking anything of it, I walk back to my dorm expected to see Alicia (she stayed the night at my place, and I had given her my cell phone to use as an alarm because hers was dead).
Alicia was not in my dorm and I figured she was in class. Since I did not have a phone on me, I got onto Ip-Relay.com and used a deaf call service to call Alicia. When she answers the phone, I see the operator type *sounds like crying in background* and I see the words come up on the screen..
"You got Jamie pregnant?"
I run from my dorm across campus to the other dorm and run 6 flights of stairs up to where Alicia's room was and she isn't there. I frantically ask to use a bystander's phone and find out that she is back at my place.
When I get to my place, she is sobbing on the coach, head in my roommate's chest (who I had known for a whopping 2 weeks). We go into my room and she asks me to get her ice cream from our freezer. I had no idea what to do, so I went to the freezer and got her ice cream and watched her stuff her face while I tried to explain what happened. Jamie had sent me a text that said "You got me pregnant, but don't worry, I took care of it." Alicia had my phone... and they actually texted back and forth while Alicia pretended to be me.
She ignored me for a week and I found out that she had sex with my roommate's best friend in spite of me and I still tried to get back with her. I was an idiot. That following year, she tried to smooth things over with me, but I had found someone else. The months following that incident were terrible and it is something that I will never forget.
I haven't talked to Alicia in over a year and currently work with Jamie on campus.
Some people say that Jamie was lying about the pregnancy, but knowing her I really do think that she was, seeing that I did not wear protection (she was on the pill).
I'm an asshole, I know.
