You have half the plot of a good movie here.I dated this gal steady for about four months. I was a freshman in college, she was a senior finishing up HS. Came up to Prom season in a month and one of the guys asked me if I was taking her. I told him I assumed that I would and he said I had better check with her. ;-)
So I ask her and she tells me that a sophomore at her school had asked her to go and she agreed. I gave her the " are you nuts? " look and she says, "I knew you would act like that. It is nothing, he just likes me and I agreed to go."
I gave her a shoulder shrug and told her it was fine and I made up my mind we were through.
So the weekend rolls around and I went out with some buds to pick up chicks. A couple of my ex-girlfriend's friends see me and a friend with these two great gals and tells on me to the ex.
This was before cell phone days so when I get home there are a half dozen messages for me to call her. I ignored them and only saw her when I went into work three days later (we worked at the same place) and she was waiting for me. She tells me that she couldn't believe I was seeing other girls.
I laughed in her face and mentioned her "Prom date" and told her to get lost. She told all of our friends that I was immature and possessive and she could not understand why she could not go to prom with one of her friends and why I was making a big deal about it. BTW all of our friends were telling her she was making a mistake.
BTW her prom date almost got himself killed as he came up to me as I was sitting in my friends car a few nights later. He was all of 5'6" and a hundred fifty pounds while at that time I was 6'3 and 210. He came up to the window and started talking crap about how I had hurt her feelings. I told him it was fine and that she deserved his scrawny behind and to go ahead and date her. Then he threw a punch at my face through the open window. I was ready for it and caught his fist before it got to my face and pushed his arm up into the front crook of the window. I then told my friend to drive and he started letting the car roll forward in the parking lot we were sitting in. The kid was pretty frightened as I kept telling my friend to go faster and soon we were moving across the parking lot with this kid hanging out of the window screaming for help. We did stop and I told him if he made another swing I would get out of the car and drop him. He retreated back to his friends on the other side of the parking lot.
I get a message at home that my ex gave to my dad that I had beat a kid up half my size the next day. I had to relay the story again to my Dad about what happened.
So this gal and I never did get back together. I went onto other things and eventually got married to someone else and had a great life.
I ran into the ex about ten years later at Wal Mart of all places. She had put on some weight (but so had I LOL) and looked like she was fifty years old when she was all of 28. She asked how my life was and I went on about my wife, my kids and how grand it all was. I asked about her life and she said it was "good".
Then she asked if I ever thought of her. I gave her a quizzical look, she then said, "well we were pretty serious back in the day."
I laughed loud enough that a number of Wal Mart people started watching us.
When I quit laughing I said, "when we were serious? Like when you went to prom with someone else?"
There were audible "oooohs" from the crowd.
She blushed and then said she that "she thought of me a lot over the last years".
I laughed again and said, "I haven't thought of you in ten years."
Again audible "oooohs" from the crowd.
She looked around realizing this was not going her way and said, "we should get together some time."
I laughed again at her and said, "not on your life. See ya." I left the building leaving her standing there.
I ran into another friend of ours about three days later and mentioned running into her.
He said, "oh, she is out?"
I said, "what do you mean, out?"
He said, "well she went to prison for forging checks a few years ago."
"you don't say?" I said and forgot about her again until I need a good story to tell.
I haven't seen her in twenty five years and I still am thankful that we broke up or I would have never met my wife.
