Anyone else feel like your partner loves you more than you love them?

I know my bf loves me with all he’s got. He’s dependable, sweet, honest, loyal, and wants to give me the world. We’ve been together 9 years altogether (broke up twice cuz of distance). Lately I’ve been toiling with the idea in my head of what life would be like it we broke up and went our separate ways for good and Cut each other out of our lives completely. And if I’m honest with myself, it doesn’t make me as sad as I know he would be. But I do love him and wouldn’t wanna put him through that kind of hurt. He doesn’t always portray his emotions but I know they run deep. I just know that if we did end it, my sadness would nowhere near match his devastation. Although there’s nothing wrong with our relationship, like we really don’t have any big drama issues, it still makes me wonder if I’m right for him and vice versa. Or if Ive just turned into a cold hearted witch. Or is this what adult love feels like? 😅 Anyone else relate?
