This is question that bitch would ask. Only females concentrate on being manipulative, conniving, and trying to ruin their ex's relationship. They are a ex for a reason. As I was told before much like spilt milk, you don't cry over missed pussy.
As was said, you'll only pushed the chick away, ignore her find a better, hotter chick. And maybe, you might "bump" into her at a mutual hangout, and she'll how well you've done, and what she missed. Pisses them off all the time.
One thing I noticed, you said she took you on vacations. Not the other way around, what else did she control? That ain't manly, and you want her back? That's playing the bitch role.
