my SO just rejected sex:(mrhkm

i know this may sound ridiculous but he started kissing me and his dick was hard so i started giving him a handjob and i could tell he was enjoying it but he wasn’t even trynna engage and do anything to me so i kinda knew for some reason he didn’t wanna have sex but i was super horny cause we didn’t have sex the night before either keep in mind this is coming from a guy who lovess sex so it’s very odd. but then i was like put it in me and he said no and i was like you don’t want to and he again said no?? so i just got up and went to the bathroom and started silently crying which may sound stupid but he rejected me and i have never been rejected like that before especially by him! idk it really hurt me. i’ve never felt this typa hurt in my heart and he won’t even like cuddle w me or hold me i find it very out of place if you know who he usually is… does this mean he is losing feelings?
