So me and my exboyfriend (first boyfriend) were going out for 5 months... He had a girlfriend before me and they went out for 10 months, but now me and him have been over for 2 months and I saw them flirting at school the other day. Me and him had sex for the first time a couple of days before he broke up with me... And the reason he broke up with me was because he had to go to an out of state college in 6 months... But there were rumors that he was breaking up with me because of her.. I guess the rumor was true, but now I feel even worse then when he first broke up with me.. I feel like he always wanted her, that he never really cared about me and I just feel used and manipulated. I know I would never ever go with him again, but the pain of everything is still there and sometimes I don't even know if I could trust anyone anymore considering he was the first guy I really ever trusted, only for him to break my trust and hurt me like this...

Sorry your first experience ended this way, and there is no going back. But you can learn after you have dealt with your own hurt, and disappointment, and be a better person for it. I wish I could help more, but the good news is this will pass with time and you will be more cautious whom you trust with your heart.
