Old school friend

At I was friends with a classmate, she and I were just friends nothing more. I went onto university she stayed to help her widowed mother run her business. So, we drifted apart and after university I got a good job in the state capitol and so didn't return. Then after several years I got a promotion, and it enabled to return to my hometown, and I bought a home close to my parent's home. In no relationship and I started meeting my old friends that were still living there. I met my old school classmate, and she wasn't in any relationship either and didn't date at all. We were soon on friendly terms and neither thought of advancing it further. But in my new job I'd to attend company get togethers, Team Building they call it. Not wanting to attend alone I asked my friend to go with me and she agreed. Nothing happened at first, but nature and fate took a hand. At one of the get togethers there was a fierce storm during the event. Nothing that concerned us until we were to head home out of the city, there was a police roadblock no traffic allowed past a couple of truck had smashed head on a bridge and road was closed until the wreckage could be removed and the police said 10am in the morning at least. So, we headed to a nearby motel and got the last available room. It only had one bed, but we thought we could share it no problems. Sleeping together in our underwear, no problems and in the morning news on the radio said 12noon was when the road would reopen. We had breakfast at the nearby diner and back to our room. Both a little bored and nothing worth watching on the TV, I was looking at her and she was looking at me. I was thinking of asking her if she wanted to have sex, but a bit afraid of ruining our friendship. She asked me did I think she and I could become more than just friends. I said certainly we could, and I was just thinking of asking you the same thing. With that we kissed and became lovers having sex twice before showering together to book out by the deadline. On our return we saw each every day and she and her mother moved in with me several months later. Mainly due to their home being purchased for redevelopment and as we were then engaged it seemed the best option. Now years later we've 4 children and her mother has now retired from her business and her daughter runs it with hired staff. Her mother watches our children. If not for the truck accident caused by the storm, we might have continued along a lot longer before starting a relationship and then marrying.
