Honest answers please

My boyfriend and I are so in love with each other and I'm honestly reading to start our lives together and so is he. Here's the thing, we've only been together 2 months. But it's like I've known him my whole life. I don't feel like it's too soon to be engaged and he doesn't either, but others do and I don't want people thinking we're insane, but we want to spend the rest of our lives together. Do you guys think we're moving too fast?
