Unexpected proposal

Hello! So, tonight my BF and I were hanging out in bed. I had to be into work at 3am so he came over to spend time with me before I came in. We were just having a random conversation like normal and he kissed me in the forehead and then said "Will you marry me?" I went silent. Confused. Humored. Stunned. I asked "Are you asking a legit question or just asking because your curious". 🤦‍♀️😂 He said he's asking and then asked me again. Obviously I said yes LOL. We've takes about it before but I was...am...stunned because it was so unexpected. There's no ring. I was impromptu. It threw me off. WAY OFF. Wanted to share... I've been laughing too myself all night.
