Moving too fast or am I overthinking it?

Met a guy not too long ago & everything so far has been great. He told me he wants a serious relationship with me. We have fun together. He took me on 2 great dates. But after the dates he tells me he loves me, and I just thinks it’s too early to tell someone you just met that. Can someone love you that soon? Or is he trying to move too fast?
