Am I allowed to be mad?

So my man does this thing where he flirts with celebrities in the comments under their ig pictures and I don’t usually mind or say anything about it because it’s not like he’s serious or he has any real chance with them but am I wrong for feeling disrespected by this? Like he’ll usually just comment some heart eye emojis or make a joke or something but today he commented under a singer’s picture and @ her boyfriend saying “@_____ wanna share?” Idk I think its completely unnecessary and disrespectful but at the same time I don’t know how to bring this up without looking like some crazy lurking girlfriend 🙄
