Well, I do have some tips...honestly, it's rather obvious that you care. When you care about a woman, they can tell. You have to act, at all times, like you do not care if they leave you. Either that or find an older girl that wants a relationship. See, young girls want to destroy you, they want chaos, they want soap opera. Older girls (30 or so) have usually figured out that all their running around and playing little miss heartbreaker isn't such a good idea...because now they can't even beg guys to sleep with them.
You can beat the young girls at their game though...they'll only leave you if they think it will affect you...they won't leave until you seem vulnerable. We're talking about very clever sharks...actually, they're more like trolls. All they care about in life until they're at leat 25 or so is causing mayhem. They want you to feel the way you do right now. If you don't call a girl after she's left or do anything to contact her, in a few days she'll be back on your doorstep pleading for you to take her back. That's because she's a child, she wants to know that you're strong and capable of dealing with these sorts of things. A child only misbehaves to see if the parents will correct them. A girl only causes drama to see if she'll get a reaction.
