Middle-Aged Love Crossroads

I am now 42 years old. After graduating from college, I worked as a designer in a house decoration company for 10 years. I fell in love in high school and got married when I was 22 after college. I resigned after having my son. I went through a divorce and raised my child alone for 10 years. When the child was 10 years old, I accidentally returned to the original company to work. Due to financial considerations, Mr. Qi and his wife faked a divorce. Later, his wife took care of their children in the United States and they lived apart for a long time, which turned into a real divorce. Later, Mr. Qi and I fell in love, but Mr. Qi faced the pursuit of other young girls. Before my ex-husband planned to go abroad to start a business, he transferred his house to my name and transferred all the money he saved to my son and me. He hoped to remarry. Where to go?
