am I overreacting for feeling bad abt this?

we’re in the gym w a friend and some girls walk by. both of them are looking at them and my bf goes “you were looking at the one in green huh?” and they both laugh and whatever. then we were talking about celeb crushes. my bf has about 10 who only 1 of them look similar to me. My bf goes hey lad look at who i’m crushing on rn, *shows him a pic of her* and our friend goes omggg🥵😍😍and my bf is like “yeahh she could get it”. Friend goes “what about ariana grande” my bf: “ughhhh nah she’s skinny. I have to at least be physically attracted to her.” Mind you me and Ariana Grande basically have the same exact body. I just have no hips and i’m pretty sure i’m skinnier. so obviously i’m in a mood now. & I told him before i don’t wanna hear how attracted he is to other women. I don’t talk about other ppl to him idk why he can’t do the same. then one girl walks by and he’s looking at her until she’s gone. he notices that i saw and makes up some shit story about how the “corner is just so easy to stare at how it’s catching his eye” so that i would think he’s staring at the corner and not her????? I confronted him abt that and he goes “yeah i only said that cus ik you thought I was looking at that girl”. He’s now saying that i’m too insecure and i’m lucky that he loves me cus if it were anyone else they’d have left me. am I being an insecure lil bitch & overreacting or am I valid. tell me straight.
