Don't be stubborn. Don't continue to sacrifice for your love. He has a girlfriend and even children. What is love to you? Even if he broke up with that woman, his relationship with the children was inseparable. You said yourself that you are in love with your boyfriend, but he still has a girlfriend and a baby. So it seems that your boyfriend is not a single-minded person, so it should be difficult for you to marry your boyfriend. Your boyfriend will leave you sooner or later, and your relationship with your boyfriend will not be supported.
