What are the chances of first loves getting back together?

I’ve heard many stories where years past and then the first loves meet up and end up together for the long run. My first love and I broke up last week. Id love to get back together and fix our problem of bickering, but im not sure thats going to happen at the moment. in time I hope we can meet paths are end up together for good.
What are the chances of this happening? Does it happen often?

I’m back with my first love.. unfortunately it took 2 years to get him back after the enitial breakup. WE’ve been going on strong for 6 months now though, and no problems. Hang in there!
