Butterflies are awesome. I still get them with jj and we've been together for almost 7 years.
I'd say follow your intuition and see where it leads. It could be just a fun time or something more, but if you don't try, you'll never know. I've always lived my life trying to have no regrets. It hasn't done any damage yet and I have no regrets of any action I've ever taken in my life.
Go for it, have fun, and see what comes. And see, you were scared of being alone. I told you that something will happen when you least expect it.
