I was hired to marry my neighbor's daughter

I've always lived next door to my now wife's family and I'm 2 years older than my wife. I wasn't much good at school and left at 16 to become a plumber working for my now father-in-law. My father got a transfer, and I was thinking of going with them. But my boss/father-in-law decided he wanted me to stay, not only to help him with his plumbing business, but his daughter as well. She and I got on very well and were friends and not in any relationship. I thought of her as more of a sister or a cousin than a possible girlfriend. It didn't enter into my thinking, dating her that is. Anyway, the daughter didn't date and at 23 her parent's wanted grandchildren and her being the only surviving child as her younger sister had died 12 years earlier being struck by a drunk driver on a school crossing, she was 9 at the time. So, as I got on well with the daughter, I was thought their best chance to get her married. I was told I would be a partner sooner if I was to marry his daughter and get a pay rise as soon as I started dating her. I like the town and was only going as I didn't want to have find my own place to live and pay rent and my parents were selling the family home. With my boss saying he would buy our family home and I could stay rent free. I agreed and asked the daughter out on a date and got a knock back, but her mother asked her daughter to reconsider as she said they wanted me to stay when my parent's left and said once I was settled in without my parents, she could stop dating me. So, the daughter agreed, and we had our first date nothing flash and then another also nothing flash. But the third date I took her to a concert in the city and she really enjoyed herself. So, she relaxed with me after that, and we slowly formed a relationship. Finally on out fifteenth date I got to feel her up and even got a hand inside her panties. Doesn't sound like much, but it was a real turning point in our relationship. The next few dates were similar and then she asked me to take her to another concert in the city and said we would stay overnight. I agreed as usual, and I asked where you want to get rooms to stay in. She said she had already booked us a room and I just accepted that. Only later did it dawn on me she had said A Room, meaning us sharing the same room. That was our first night sleeping together and we had sex before the concert and after the concert and the following morning as well. Pressing my luck, I asked her to marry me. Even as I asked her, I realized I might be being too haste. But she said she would think it over and at least I wasn't refused straight away. A week later she told me she accepted my proposal and wedding plans were made. Our dating also went up a notch as sex became regular and she stayed over at my old home with me. But she was taking precautions and only stopped the week of the wedding. Within 4 months of the wedding, she was pregnant and would've our son and now I'm a full partner with her father as my wife had gotten pregnant again and so her father made me a partner. Tests show it to be a girl and we plan to name her after her late sister. I've also realized something around the time of our tenth date I really loved her, and I think she realized that I did soon after and or before I did. So, she started to allow me to go further at my own pace at first and as I was so slow, she ramped it up with the second concert trip.
