The person I liked was checking me out when I wasn't looking?

Today, the person I liked was checking me out when I wasn't looking when i was leaving. I thought about asking her out, but I don't have very good confidence skills with the ladies. For a guy with very good confidence skills, he can take her to bed less than 20 minutes , then they either start dating or friends with benefits. I don't want to sound low, but there's way better guys for her than liking me since around last winter, when she signed my birthday card... I could ignore her or wait for someone to win her over... some reason she still wants me, then move on to someone else. I don't know... maybe I can find a guy who is BIG down there, if you know what i mean, and see if there are a better match then me.
