Relationship I Education.

Some friends of mine told me that i always push people away when they get closer to me?
hwaaa i'd never meant to do that,really.
i just dont want for having a relationship at this time,and for heaven sake those people who try to gettting closer i only admit them as a friends. i know their act,their attitude,the bad things from them. and i cannot accept them easily,really.
i just haven't met the right person. and i dont care those people who judge me about me doing these rejection things.
Education is the only thing that i could think right now. and i promise to myself not too playing around and do some silly things too much. Eventhough i cant help it with the travelling and movies things :p
God,what should i do then? :(
