Broken heart 💔

My SO and I were planning on trying for a baby this summer. I graduated from school I'm just doing an internship before I take my state boards. And just thought it'd be the perfect time. Now he has taken it all back and saying he doesn't want anymore children ever. He has 2 other kids. I'm so broken hearted. I can't be with someone who doesn't want a baby at all. He said he won't change his mind. He's asking me to stay but idk if I could see myself tied down to someone who doesn't want kids with me. I'm torn. I live with him in another town from where my family is. I took my internship down here and idk what to do about that. I'm 6 weeks away from finishing it but idk how that's possible. Please please help me give me ideas words of encouragement something!
