first you don't fell uncomfortable about this! this is common, you have different feelings that doesn't mean you are different, if they don't understand you then leave them, no need to be in touch with them who don't understand you! except family .

Your roomate should have never told her , you should have told her when you're ready. But now it happend , so what you can do now is talk to your crush , and if they say something good/hopeful , stay . if not , just leave and by time , your crush of her will decrease and you'll be okay. Best of luck !♡
