More recently, last year, about 6 weeks after we started dating, my current girl had a ONS (she swears this was the only new guy since we first started dating in September). It wasn't cheating because we never made a commitment to begin with.
1) Said goodbye with hearts.
2) 7 days went by as she went to Las Vegas after turning 21 and getting a boob job. She wanted to move there and be a show girl at the time. Then she said she wouldn't quit stripping for anything. A guy had just handed her $8000 to get fake boobs.
3) I got a message saying "Thinking of you".
4) When I wrote to confirm our plans for the next day, I got no reply.
5) I wrote again and she said she wasn't feeling well.
6) 3 weeks later she said she feared me.
7) We got together and I asked her if she was with someone else and she said yes.
8) She reminded me I was with 3 other women since her.
9) I told her I liked her the best, and she said she liked me the best.
10) We had mad, passionate sex.
11) We made love for the first time (compared to regular sex).
12) She said sleeping with that other guy made her realize how much better than average I am in bed.
13) She started saying "I love you".
14) We've been going strong since.
15) Now 5 months later, she can't stand stripping and wants to give it up ASAP
Many men say I should have dumped her for "cheating" (before a commitment). On the contrary, looking at the bottom line factor, I should send that guy a thank-you note and force her to sleep with him any time things go south.
