Did i blow it? jealous?

there's this girl i met in a party and we kissed, remained in contact after that. but then we met recently in a town activity we were roaming together until we met we her friends(boys) which were my aquantances i left her wit them as they were kinda childish n she was huggin one of them a lot that i may have gotten the wrong impression. i text her 2 days after asking her about it she told me the guy was like a brother tld her i was jealous kinda feel like a jerk cause i left her wit them and treated her bit cold(nt badly) we not really an item yet bt feel like i blew it any idea on how to gt d spark back. i askd her out again after her xams she agreed!
