As people have been saying, i also say that you must BECOME a man, not get a posession, really think hard on why do you want to get a girlfriend, the answer will show how prepared/mature you are to be in a relationship, really, if you are immature about it, you are doomed, a relationship will be a bad experience in the long run, it happened to me...
What i mean by beign mature is that you must become a man, overcome personal problems, become healthy, become happier, become independent (meaning you mother and father dont support you any more), understand how to make you partner happier, otherwise youll attract what you are, if you dont have a healthy personality, youll attract someone who also isnt healthy, what an explosive combination for sadness and unhappyness!.
