Yynatago: Thanks

Believe it or not, I already knew this far, I already follow these guidelines, but it's not enough. I mean, I've been already told I was too clingy, so I even got to the point of counting calls and counting how often someone initiated the conversation! I believe that I shouldn't have a "balanced" relationship, where I give as much contact as I receive, because that still won't keep people from running away when their feelings are too strong, compared to what they are willing to accept.
Also, I know it's normal for some people to drift away. However, it's another thing to just lose interest and eventually stop contacting each other, and it's completely different to disappear out of the blue. I'm talking about situations where we contact each other once or twice per day (not just me, mind you, I do keep the balance), and suddenly they are nowhere to be found, and a few days later, when I eventually decide to call, they won't answer.
I'm seriously thinking of becoming rude next time...
