falling in love?

I have not been falling in love for quite some time.. During this period I feel great on that.. However recently I think I am about to fall in love.. I really scared to get hurt before a relationship starts.. Perhaps in this sense I really look like a girl.. But if having a girlfriend then will be a different case.. Because can share with her everything and do not need to keep on hiding the feeling.. ish.. I have no idea what I am saying.. Of course i wish to have a gf.. but at the same time I scared to be rejected as well.. Do we really need to go through no pain no gain?
