Am I Wrong? Is it Love or Need?

I'm 26 and was in a relationship with a man who is already married and has kids. I worked at his place. In the beginning, he told me he was disturbed by his wife's behavior. He forced me into this relationship and used to say that I saved him from his toxic marriage. As time passed, I also started loving him. After four years, when my family pressured me to marry another guy, I asked him to marry me. Then he started ignoring me and making excuses. He wasn't even ready to listen. I'm very serious about him, but he is making fun of my situation. Now I'm suffering from anxiety and insomnia due to his behavior. He has started loving and caring for his wife and kids again. His love for them has grown, and I have become alone as before. What should I do?No hope in sight.
