After my first divorce back in 08', used okcupid (back when it was free and decent) and got a message from a philipino girl who was 14 years older (but didn't look it at all) lived like 3 miles away, and figured what the hell. It was pretty fun at first (she came family money so didn't work, and I was waiting for my new job's training class to start so all we did was hang out and bang.)
Coming from a marriage that sex was used as a commodity it was quite a refreshing change, although she was insatiable and it got to the point I had to sleep on my stomach or she'd "wake me up".
First red flag was when we went to the Scottsdale mall and while buying a Louis Vutton purse for herself, she had me try on (and then offered to buy me) the 007 Omega Seamaster ($3,500 at the time) and I had to decline. I mean that would have been an awesome gift but having someone you've only known like 2 weeks offer to buy you something like that is not normal.
Second red flag was after meeting my friends. Got along fine and then right when we left their house, she was insistent that all of my friends girlfriends wanted to get with me, which was ridiculous as they all had been together for years (2 of the 3 couples are still together, 17 years later), it was clear she was just jealous and threatened by them because they were younger knew me longer but did it in a way to stroke my ego.
Flag 3 was when she started speaking in a British accent out of the blue. I still have no idea if it was done in a joking manner but it was full-on 100% of the time for an entire day, then it just stopped.
The last straw was a few days after that when we went to a poker party at her friend's house. There were probably 30 people with multiple tables going at once but as I didn't have any money (just started the new job) I was just hanging out and socializing. While smoking outside some girl that was a friend of the host came outside and smoked and we chatted for a bit and got along pretty well, but apparently she (the girl I was dating) saw that and apparently we had to leave right then. The instant we got into the car, she was trashing that girl calling her a whore and how gross she was and proceeded to talk about them the entire drive back to her apartment, which was a complete 180 from the impression I got from that girl.
I broke it off as it was clear that she was insanely jealous of any girl I interacted with and didn't need that sort of poisonous drama, I do miss those perfect eraser head nips though.
