Guy's Behavior

The guy I like and that I thought that liked me back just told me he's now in a serious relationship?

so.. there's this guy and we've been back in forth for almost a year.. in the beggining he seemed to want something serious and i didn't want that he would drop some hints about him being in love that we'd look good as couples etc and by my answers he realized that i didn't want a relationship and started to get weird with me in the mean time i missed his attettion so i kinda chased him back to my life and now he was the one telling he wanted nothing serious.. we would have some silly fights but he ALWAYS came after me everytime i would try to let it go he shows up not a week ago he asked me if i dindt feel not even a little bit of jealous of him bc he does of me and hates seeing me with other guys so i told him that i dont bc he's not mine (maybe i was a little harsh) and asked him why would he feel jealous and he just looked at me like i was dumb.. two days later he told me that we had to talk.. SURPRISE.. he is now DATING another girl? wtf and made sure to tell bc "he's a faithfull guy and knew that sooner or later something would happen between us again" WHAT DOES IT MEANS? knowing that i just told him that i was deleting his number and that he should do the same but he's just started complaining telling me to not do this and that he would never delete me saying i was overreacting andit wasn't necessary ofc it is UR DATING and my heart is broken just like that evanescence song:(
