Can i find happiness being alone?

im 20 and ive just never been good with girls. Im not fat or ugly, i guess im just dont have that smooth element that girls want, and i guess im not all that confident and im kinda shy. But anyway ive only had one GF and that ended really nastily, it i think it even furthered me from being compatible in a realtionship, and every girl that i would even like in the future would most likely be with some other guy who would pick her up. I know everyone says try to be that type of guy that all girls like but.......well you know the saying "a frog doesnt look good in a fur coat" well thats how i kinda feel. So are there any of you that have found being alone can be happy too
