im struggling with being single...?

i think im a pretty good catch. There are guy that i like but nothing seems to be going anywhere. I'm not desperate in that i won settle for just anyone, but I am desperate to find that someone. does anybody have any advice to offer? whether just comforting words or tips on how to find them.

also a separate issue is that there is one guy that i think i could grow to like based on his personality but the only reservations i have is that he is so thin that i'm not too terribly attracted to him physically. I mean i like his face and everything else, he is just so... scrawny. that seems shallow. i dont want i big buff guy. just normal sized. so any advice there would be appreciated as well.
