Cruising into Marriage

So, we work together... He apparently like me the moment he set eyes on me and thought I was so sweet. Lol!! I thought he was cute, but to young for me and we work together. Well after work a few co-works would go out for drinks and other nights we would go workout at the gym. One day we both were just walking on the treadmill and he ask me to lunch, I of course, being the blonde that I am, I asked what time his lunch was (meaning work lunch). He says, no no, I am asking you to lunch before work like on a date. We works nights together, still do. We had Thai food and been together ever since, 4 years in Sept.
