Is there some kind of meaning behind it or was it just a hug?

We had dated for 3 months... (almost nvr leaving eachother... suffocated both of us) after things got bad i nvr rly got a why, only thing id heard was from her mother telling me to wait, contact stopped almost entirely, pyhsicaly espescialy, a long 15 months later, she's having trouble one day and i stop in, things went well... she tried(which was unlike her usual cold bitchy behavoir for the last 15 months), she gave me a hug... out of all the times... i looked like an idiot standing there like what no hug, :\ was it just a hug or...
