Should i ask her to come or not?

A few years ago i met this really great girl on cruise that lives in the same area as me. When we got back we went out for a couple months but it didnt wok and we broke up. For about a year after that we still saw each other every once in a while, but only with groups of friends. we talked a bit on facebook, but eventually we just stopped talking, its been about 2 years since ive seen or talked to her. i recently came across 3 Bon Jovi tickets. i sent out a m text not including her because its still a little awkward. one of my school friends accepted, but the other people i invited cant make it or dont like Bon Jovi. I was thinking if i should ask her over facebook.
