Im giving up

Im a 16 yo boy. Im recently single from a two year relationship straight out of highschool. We broke up from a lack of communication and she saw me talking to a long time friend of mine whom is a girl and that was that. I just dont want to be in a relationship again straight out of highschool. I am tired to be hurt and betrayed in all of my relationships. Im recently in a community for help and support in this matter and its not a long term cure. I am so tired of the lack of concern these people will have for me. I would give up my feelings to never feel hurt again. Unless i am drunk i dont think about a relationship. Im better off alone
