Well, where do I start? My very first girlfriend didn't technically cheat on me. She dumped me and then proceeded to mess around with my best friend, who had been my go-to guy when I was upset about the break-up. He told me to just get over her and move on while neglecting to inform me that he was getting busy with her behind my back...I'm guessing he felt bad and didn't like a side of guilt with his blow job entree.
I have actually been cheated on a few times. The first was a girl I had a semi-long distance relationship with. She was an hour or so away, but that's far when you're 17. She had this guy friend, Shane. He was older, probably 23-24, and would hang out with her late at night after he got off of work. I did *not* like this, and made my displeasure known. She assured me that he was "like a brother" to her and not to worry. Right.
One day, she was acting really odd, very quiet and mopey. I asked what was wrong, and after what felt like pulling teeth, the truth came out. She and Shane had had some drinks (which he provided...to a minor) and made out. I was angry, and felt my fears had been justified. Oh, justified they were. When I asked if that was all they did...there was silence. Then she told me that she also have him head.
That's when my phone became a projectile missle into the wall.
She kept calling back, asking for forgiveness. I took a walk at about 2am, and when I returned, I called her back and told her I never wanted to see her again.
There was also the girl who was dating another guy at the same time. I had dropped her off at a "friend's house" the night before, and she was supposed to call me when she got home that night. She never did, and we were meant to hang out the following day. She never showed, never called, wouldn't answer her phone. I was worried. I call her mom...she has no idea where she is.
Now I'm *really* worried. So I get the idea to go back to the house where I left her the night before to see if they know where she went. Lo and behold, she's still there. She spent the night. With the guy who answered the door, asking if I was her brother.
I tell him that no, I am her boyfriend. He seems confused. He then tells me that I should know that she spent the night in his bed, and they'd been making out. I find out later that there had been far more going on, and she had been with him before she even met me. She apologized and begged for me to forgive her but yet again...I told her to take a hike.
I guess you could say I've cheated. I once kissed another girl while in a relationship with someone else. However, the relationship was, well...crap. I broke up with her the very next day...so while I'm sure it does count as cheating, I don't feel like a total piece of shit.
