I married my ex-wife's sister and we all live together. Are there any other people like us?

After my ex-wife and I got divorced, I married her sister because she kept calling me and asking me out. Now, I have children with both of them. I live with my current wife, her sister (my ex-wife), their mother, and all of our children. I am still on good terms with my ex, and last Saturday, we all went out for dinner together with all the kids and had so much fun. The problem is, now I have to support all these people (my current wife, my ex , all our children and my mother in law) all by myself. I'm currently a regional airline pilot and my salary isnt big enough so I drive uber when I dont fly. But I guess it will get better if I ever make it to a major airline and the kids graduate. Are there any other people out there like us?
