HELP My hearts been broken what do i do please read all details i know a lil long but please need advice?

Just because she doesn't like you as more then a friend, doesn't mean that she absolutely hates you. It is actually nice that she told you instead of leading you on further. But, she should have been honest from the start. Lay low for now, and let her have her space. You guys are just friends now. But DO NOT as her to go to a movie or anything, because she has a boyfriend, and that is weird for her also. Maybe the thing with the other guy won't last, and then you can make your moves. Don't be mean to her, and keep being sweet to her, in hope that she comes back to you. Im sorry you are going through this!! Hope I helped! :)
