I've unwittingly been the other woman... twice!
In my life I've had 2 relationships where I've thought the guy was faithful but I was wrong! They had girlfriends before they hooked up with me. First time I was 17 and seriously into this guy Ryan, he was a typical bad boy and I found him irresistible. One night we were hooking up at my friends party and after as we were leaving hand in hand, we ran into this girl who as soon as she saw us started to cry, she screamed "2 years Ryan! I've met your parents, you were my deb partner and you cheat on me!", I just got the h*** out of there, I never spoke to him again.
Second time I was 18, I was crazy about this guy Damian who I had met 2 years earlier, I was 16 he was 22 and we had a Danny and Sandy style summer fling, he was in the army in another state but his family lived 1 hr from me so when he came home, we started going out, he was my boyfriend, I was his girlfriend the whole 9 yards or so I thought! We had just celebrated our 3 month anniversary, we'd gone to dinner at a beautiful restaurant, he'd brought me a brand new digital camera and we had met up with his friends and had drinks the night was going wonderfully...until... We were all walking together to another bar and his phone rang, I told him to answer it but he didn't, he said it was work and wasn't worried. Throughout the night as I stood by him I felt his phone vibrating but he just kept drinking. So we get back to his place and were full doing it, going off and we hear a car pull up then a knock at the door. I pull on his shirt, he put pants on, we go to the door and there she was all 200 pounds of her, screaming at me calling me a home wrecker and a w**** so I bit back telling her to step off that I was his girlfriend and it was our anniversary, she said "I've been his girlfriend 5 months! I'm pregnant to him!"
I flipped out completely! I punched him square in the face, elbowed him in the gut, kicked him in the groin and stormed back to his room put my dress and heels back on, grabbed the camera he brought me and came back out he was still on the floor and she was comforting him I threw the camera down the hall as I left I looked at her and said "hope you like being cheated on sweetie, call a child support lawyer now, this p**** will be long gone before they cut the cord". I was right. I ran into her 4 months later, she was huge and she came to me and said he'd run back to the army 1 week after she caught us.
