Consider this... if your previous girl bought you a 360 or PS3 wouldn't you be using it? And if so wouldn't you be pissed if your present girl had a problem with you using it?
Great post. Unless she's crying herself to sleep holding the locket and moaning "Billy, I miss you sooooo" don't worry about it. Otherwise you just come off as insecure and jealous.
