Ruining my relationship

I have to admit, I have alwYs been the most confident woman. Especially in relationships. The past few months in my current relationship. I have been so insecure. Felt very unattractive. It’s crazy cause my Partner takes me out, we have tons of sex, and he’s always here. It’s mainly when we go out and he tends to point woman out, but never says anything and when I agree with him (im bi he knows it) it becomes weird. Today we just had a set back. By point out I can see his wandering eyes. I get it it’s just a look. But if he brought it to my attention to stop (cause i use to look hard at times too) but stopped. So should he. At least respect a little more. Idk am I overthinking this bs?
