I have a problem about relationships, but not about being insecure or something like that, let me explain. I can talk to girls. I don't always look for a relationship, but sometimes there is a girl a really like, so I start talking and dating with her, she says I'm attractive (not Brad Pitt, but I'm attractive), that I'm funny, interesting, smart (by now you must think I'm a jerk for saying this, but it's for all you to understand) and that she likes me. Things are like that for a while (a couple of weeks, sometimes more, sometimes less), we even get to have sex and it's awesome, but after a while, they just stop talking to me, I don't know, maybe they get bored, I really don't know why. That's my problem, and it's kinda sad, because I really get to like some girls and it hurts when they just disappear, maybe you have some advice, some explanation about what may be my problem. I feel kind depressed about it. Hope someone can relate.
