Life after Marriage

Married for 10 years divorced by her because I wasn't the man she had married. She used use to brag she made what I am and then she decided she preferred the old me better. We have 8-year-old son and I get him every other weekend and half the holidays. I've a great career and do very well even with the child maintenance I have to pay, no alimony as she has the same career and she thought it would make her look less successful in her career than me. I just moved on with my life and only looked forward to my son visits. Then in November 2021 the house next door was sold, I got some new neighbors just a mother (widow) and her daughter. The daughter is the same age as my son, he was staying with at the time. He made friends with the daughter straight away and I met the mother, but she was busy settling in, I didn't see her much after meeting her. Luckily my son goes to the same school as the daughter as my ex only lives 5 blocks away on the other side of the school from my place. So, the daughter already knew someone in her new class on starting school. Her mother is also has a good career and had moved because of a promotion. My ex met a new man and was invited away and asked me to take him while she was away. He could've gone but it wasn't really for children (gambling), he would've spent most of his time in supervised care. Of course, I said yes, and we had a great time and we hung out with our neighbors most of our spare time. I started dating the mother and after several dates we started a sexual relationship and were getting along very well. Then in May my ex told me she and her new man were marrying and going overseas. I wasn't happy with the thought of my son going overseas and all the hassles getting to visit me it would cause. Neither was my ex-wife she said it would cause heaps of problems and told me she was willing to leave with me and no more maintenance payments. But it didn't mean I had full custody and we would return to previous custody on her returning, also she could get anytime she was visiting. I agreed, so I've my son now fulltime unless my ex come back for a visit. Also, I married my neighbor last month due to her becoming pregnant and they have moved in with me and my son. @Two years after my divorce was final, I was married again almost to the day.
