I think I like my bfs best friend

I’m looking for some advice about a relationship situation. I’ve been dating someone for about two months, and he’s a good person, but I’m realizing our personalities don’t match as well as I expected. I’ve also noticed I’m not feeling much of a romantic connection, and things aren’t really progressing for me.

His close friend, on the other hand, has a personality that I click with much more. We get along really well, and it’s made me reflect on what I actually want in a relationship. I’m not acting on anything, but having these thoughts has made me feel conflicted, especially since I was already unsure about continuing my current relationship.

I don’t want to hurt anyone or be unfair. I just don’t know what the most respectful and mature thing to do is. How should I handle this?
