Love triangleeeee....?? HELP?

heads up in advance, may be long.





well ive known him for.... 4 years?? ya. last year we finally started talking TALKING. this year we got more friendly. in class he would grab my hands or i would play peek-a-boo with him when he was tired and he would smile so huge. he would text me constantly and he got up at 5 in the morning when i asked him to be my running buddy and everytime i asked him if he'd want to start running cause i was walking he said whenever i wanted to and made sure i wasnt near the street. he was hugging me and picking me up one night and stroking my hair. hed tell me goodnight and give me huge hugs. he would lend me his jacket even if i wasnt cold and would always scoot closer to me in class. he'd keep his leg next to mine and if i got tired would let me rest on his shoulder. he begged for me one night to go dancing with him at a friends birthday party thta i didnt even know but i couldnt becasue i was grounded. he even came with me the day my abusive ex got in my face and would stand in front of me every time my mom got in my face and would take responsibility for any action I did and would turn back around and smile. my teacher in which we have the same class says were the sweetest together.





im really at a loss here. a few months ago he got a new girlfriend, and we've personally watched eachother come in and out of relationships. since then... the lovey dovey thing is gone. now hes the type of guy who dates a lot only because A LOT of girls like him. me and his friends all admit he's sadly never fallen in love with any girl before which is sad. im the type of girl whos dated twice one a long distance i never saw the guy, the other my abusive jerk. he always listens to me no matter what, and everytime i get sad he'll try to cheer me up. he even gave me his 5 dollar bagel once to make me feel better. (i dint ask i promise, i didnt even hint) he would write cute things on my paper and would make jokes, play games, mess with eachothers computer, the whole works of a really cute couple right??.......well the other day he was talking about his girlfriend all class, which he's never done before. he didnt even wait for me after class like he always does. he just left. no goodbye no nothing. later i texted him that ngiht and he was all for conversation....im really not surre if im being replaced by this girl or whats happening but some advice would be great. please please please.Love triangleeeee....?? HELP?
Well maybe he's thinking that if you and him aren't goin anywhere (relationship-wise) that he might as well ';have fun';. He sees that other girls like him so he might just be going out with them to make up for the non-relationship yall ahve. Cuz guys get bored after going after a girl if the girl doesn't do anything.
