What if anything can I do about a relationship I just left after being with him for 20 years?

We weren't married when I left in February of this year we divorced 10 years ago but that way you stay together for ten years after we divorced because we basically got divorced because his family wasn't going to help us anymore and we needed help with our children financially and they weren't going to help if he was with me so we got divorced but as soon as we were stabled and got on her feet will your moves right back in together and have lived together every since we were buying property and I say we I did sit at home and I didn't work and that's something he is going to make sure that he tells y'all but I did so because we had four children and it would have been ridiculous to pay child care for for children it would have took my whole paycheck plus some of his just for child care. During this time however he started a business and he would have been able to do so had I not been sitting at home with our children I could have made the choice for him to stay at home with the kids whi
