so me and this guy have been dating for 10months and he was the love of my life. alot of firsts with him and i was alot of firsts for him. well jux say we both were first loves to each other. but anywho-we broke up after 10months bc he was too busy and i was too busy and we hardly saw each other, and he started talkin to other girls. we didn't talk for almost 2months after we broke up and within that time, i met someone else, but it didn't work out bc i still had feelings for my ex. Once me and my ex started talking again, we met up at an old spot by the creek and on the train tracks where we'd watch the sun go down and talk, and when we were there he talked bout how he missed me and how we'd get back together as soon as summer was over bc he had been busy with baseball for the remainder of the summer, he also said how much he still loved me and was sorry for hurting me and i.e. before he left, he kissed me, a longer more passionate kiss than jux a kiss. Three hours later before i went to bed i checked my messages and he left me one saying "sorry, i didn't mean to lead you on but, i have feelings for another girl." my heart shattered but for some reason i still love him. this other girl isn't pretty and she isn't nice and i'm pretty sure the majority of people would agree. i miss him a lot and i don't kno what to do. is he serious with this girl, or is he just getting me back for being with someone else awhile after we broke up? i want to move on, but then again it hurts, and i miss him. its like i have a feeling that when school does start, we'll b together again. but theres that other girl. what do i do?
