I feel like my bf is unsure of me

This evening my dad asked me if my bf and I are planning to get married already. We don’t have any plans yet. But at the beginning of our relationship, we made it clear to each other that we’re dating to marry. I told him about the conversation with my dad and idk.. his reaction was not what I expected.

He told me that marriage is not on his mind yet. He was kinda taken aback and asked me if I was thinking of getting married already. As for me, I don’t have a concrete marriage plan yet, but I do have an idea. Like I would want to get married to him in 2 years or so, but it seems like he really isn’t thinking of marriage yet..

I feel like he’s unsure of me while I’m certain that I want to spend the rest of my life with him. Don’t get me wrong.. I love him so much and I don’t doubt his love for me at all. I just feel uneasy that I feel like we’re not on the same page.
