My bud dated this girl, they were engaged for a while. I was the one that intro'd them years ago and originally I wwas going for her but got sidetracked by her best friend. So they dated for about 1.5 years and got engaged... All the while he was a bit of an ass, and always flirting with girls, and while they were engaged he would make out with other girls etc.. They broke it off, about a year ago.. Lately I feel us getting close.. Anything wrong if I take it to the next level?
