Then you gotta be player. If she is playing with everybody then you gotta play like that too. She is having fun and fulfilling her physical desire. She is having romance and having fun in sex. It’s just a simple human desire where she fked love. I don’t blame her thou. It’s understandable that you can’t leave her easily and you want to get her back no matter what. I respect your love. If she wants to be your friend only then, be her friend. Do not let her know your weaknesses anymore. Take her company (that’s your satisfaction for now) and move your life forward. You gotta be something first and you could get whatever you want after that. I know emotions are not that easy to control but don’t do stupid things (like I did a lot and almost fked my life). Do not fk your life and finish your study on time. Love is everything. Start living life as her friend and take some time. If she comes back then you guys are good to go. That would be more mature love.
