AITA for considering a divorce because our sex life is boring?

I've been married to my husband for 5 years now. Like every other relationship, we've had our ups and downs, but there's one particular problem we can't overcome: our sex life. My husband doesn't want to try new things in bed. We always do the same thing, and whenever I suggest we try something new, he stares at me weirdly, like he doesn't recognize the woman in front of him.

I've asked him why he doesn't want to try these things with me, but he always changes the topic or says things like, "Since when have you become this person?" or "You've changed." This made me feel like I was the problem and that what he was saying was actually true. Despite feeling unhappy with how things were, I didn't want to destroy my marriage because of this reason.

However, I can't help these emotions that I feel. Here and there, I can feel myself resenting him, and these feelings keep growing. I can't seem to understand why we could work everything out but this one thing.

So, AITA for considering a divorce because our sex life is boring
