When a girl gives eye contact after a hug... good sign?

I hugged my crush goodbye before we had to leave for the summer. We knew they are chances We might not see each other again if I failed an exam, so she wrapped her arms around me , and caressed my back while whispering 'Good Luck' and while we separated our arms we still around each other and looked into each other's eyes for a few seconds while she smiled at me...

any chances this was a romantic hug? it's hard to decode them...
