25 and he 28 with 3

Sooooo i been knowing this guy for about 15 years now he was my first love in moddle school and we finally decided that we will try and be a "real" couple...... well the forst time we had sex there was no condom and her made it very clear he didnt want to upset me so he would use it the next time.... well long story short they havent been used and i really want a  baby but he already has 3. He's made statements like ion want any more kids less im married or the woman im woth is going to be around. But idk if i want that as well.... i just want my child i been trying for so long and just had a miscarriage and i just want to be a mom so bad its depressing me. What should i do.
