bf told me he’s gotten better head

my boyfriend(32) told me(19) last night that i’m not the best head he’s gotten after telling me for over a year that i was. i asked him about it after he looked disappointed after receiving head. he looked like he was on the verge of telling me anyway. i asked who and to my surprise he already had 3 names. i know i asked him but damn it still hurts. i feel like i don’t want to bother giving him head anymore because i feel like what’s the point? then my dumbass asked why and he told me why they were better. he also asked if i wanted him to list more? it didn’t seem in a mean way but idk i can barely look at him the same. i’m so hurt y’all i need advice. how would you feel in this situation? am i just sensitive?
