Is Having a Celebrity Crush Cheating ?

so my bf and i have been together for about 8 months and i’ve noticed every time i talk about a celebrity and call them attractive he gets all mad . he says no go be with them or ohh yeah he’s so hot right ... and it honestly annoys me because like how am i supposed to be with them.. THEY ARE FAMOUS like that man doesn’t even know i exist... and i’d never have a chance with them anyways so what’s the problem. I honestly wouldn’t have a problem if he called a girl celebrity pretty or anything BUT if it was like a local or something then i would be upset you know ? but a local and a celeb are different bc you could actually have a chance with a local lol. Every time i tell him to chill out he will be like you don’t love me or i’m not attractive enough for you.. which also annoys me bc if i didn’t i wouldn’t be with you in the first place .. anyways have you experienced something like this or similar to this?
