Word! Lesson learnt the hard way! My fiancee over a decade or so ago pestered and manipulated me into paying for her bolt on *******, yep $5000 or so. Then she was pissed off I violated the Engagement ring cost rule, and she was embarrassed when with her girlfriends, and then it was that Classic Corvette, she wanted to buy and wanted me to go half-in on, and then that 7 passenger SUV she wanted to buy because her colleague had just bought one, and she was driving a 6 year old Isuzu.No disrespect...but I can tell by looking at her she's high maintenance.
My first wife had bolt on ******* as well (that I paid for...$5000) and she worked out at the gym 5 days a week oh and she entered swimsuit figure competitions as well. My advice is keep her as a girlfriend and have fun, then when things start getting serious, run, run far far away and move on. If she's already "killing me" as you say I think you've crossed that threshold already.
Hot *** and a pretty little thang on your arm to show off to the boys gets real old, real quick when the whinning & demands start.
Gawd I was so dumb in my 20's. The other head was doing all the thinking...
