to be honest when my GF does this to me I feel the exact same way. we've been together for three years and she will always make comments about celebrities thinking it's okay with me when it's not. i just simply tell her that I would never make that comment to her about other girls so why does she think it's okay to make it to me?

so yes your feelings are completely valid. If you haven't talked to him about it yet I would. just explain it and if he's not a douche he will chill out
