How long did it take you and your boo to become official?

So I’ve been seeing a guy exclusively since November. We met on tinder at the end of November and we clicked right away. We live in the same small village, about a 15 minute walk from each other and out social circles overlap quite a lot, yet somehow we never met before tinder. We even went to the same high school but he graduated before I started. It really is like fate was waiting for the right time for us to meet. Since November we’ve become almost entirely like a new couple. We have such a spark, it’s really quite beautiful. I’m a traditionalist so I’m waiting for him to ask me the official question. I’d love to know your story about when you and your SO made it official? When did they ask you? Did you ask them? How long before they asked?
