It took about 6 months for me. I was always on the fence, for some reason. We went on a trip together where everything that could go wrong, went wrong--missed flights, lost hotel reservations, etc. This was so frustrating for me because I'm a pretty organized person and nothing went as planned.
He was amazingly chill about everything and he made me see the fun side of all this mishap. I specifically remember the very moment I knew I was in love with him.
My work mistakenly made a reservation at a hotel specifically designed for families with kids--In each room, there were cartoon drawings on the walls, video consoles, and bunk beds. My now-partner just laughed so hard (because it came at the end of a crazy day of traveling) and then got so excited about the kids stuff in the room. That was the moment.
