relationship advice!!

I really want to be in a relationship. I miss having someone (I'm fine with myself i don't rely on boys to make me happy but I just miss relationships) It's just been soo long and being single can be v fun but I've been bored of it for months now. I do like this guy who goes to the same sports club as I do. The only problem is he's the only person I feel awkward around, I don't know why! I'm a confident person and usually even around guys I like but nope I always get so nervous when he talks to me or sits with me. Anyways any tips on how to get myself dating asap?
