Im very new at this, sooo I may be wrong, so please take what ever I say with a grain of salt

I think this is an on and off again relationship.. That these two people will always yearn for each other, but just cant seem to make it work.
Maybe you guys loose touch with each other, and then find each other again... Yet neither ever really lets go.. But there's just that "something" that it wont last...
Jus my two cents.. Sorrree I could be more helpful..
