My Neighbor's wife

I'm a widower 51 and live alone my 2 children have their own families now and visited most holidays. I've a loudmouth neighbor who is thinks he knows everything but isn't an expert on anything except for talking shit. He has a nice-looking wife who he treats badly, I became friendly with her and realized I was her only true friend. All the other people she knew were like her know nothing husband and talked similar shit. They had no children and so when he died in a drug and alcohol fueled car accident, she was left alone. He kept driving straight when the road turned, he didn't fare well in the 100 or so feet fall from the road. The car burst into flames on hitting the ground, she was lucky she wasn't with him. I helped her as much as I could and soon found out she would've to find job and another place to live. Neither were looking good, so I took her into my place, she became my housekeeper 38. Then on a stormy night she joined me in my bed and became my lover. She still sleeps with me no 4 years later and I've decided to marry her and try to have more children with her. I've been told by my 2 existing children it would be perfect solution for us both.
