Currently not, I've been in a long time and serious relationship for 4 years with quiete the perfect girl, people were asking us if when we'll get married... But over the years our passion faded and in the end we were just an intimate friends (and not very good ones). As the passion faded we've both started noticing the mistakes about each other and soon after than we break up. And when we broke up I wasn't really feeling any sadness, I was actually happy as the relationship was really smothering in the end. Right now I'm trying to avoid getting into any relationship, there are girls around that might be interested, but for now I just wants to be free. That might change if I meet someone really special, but as of now, no thank you.
And girls liking nice guys... well that's it if you are their brother or best friend. I've been "nice" guy once upon a time, but through my experience I've soon learned that that's a bit bullshit. There is a dozens of book written on the subject, there are behavioral studies and what not. If you are jerk and have the cash, you are a fucking god. But nice guy with a big pile of money stands a chance aswell.
