I'm ready he might be?

Kayla
I was reluctant to move in with my bf before being engaged and planning a marriage. Due to extenuating circumstances we moved in 10 months ago. We've been together 3 years and I'm ready for marriage. But so far no ring. He says I need to be patient and that he wants it to but it's not the right time yet. I want to stay positive but how do I remain calm and patient when I'm so ready?
