Well, I've been the same way before, but honestly searching specifically for a gf is just asking for heartbreak. You might have the best intentions and want to treat them amazingly, but if you try too hard you're far more likely to end up with random girls looking for a bit of "fun" who will casually drop you.
The nice girls who actually want a guy who just treats them nicely tend to be extremely cautious, since they don't want to end up with a fake nice guy who just wants sex and will take advantage. You wont find that type of girl on dating sites or hunting desperately for a bf. They tend to wait until they meet a guy they're really close too and feel they can trust 100%.
So, best advice I can give is to simply try to make lots of friends. Make friends with both guys and girls, not just girls, it'll help your social confidence, give you people to talk to and your guy friends might introduce you to more girls anyway. Try not to even think about wanting a gf. One day it'll just happen, when you least expect it. Best of luck
