I need help with my bff problem with her man.

Ja
My best friend for six years has her own family. And she got pregnant end of highschool with her highschool sweet heart. Now her daughter is one years old. So far so good but now she comes to be crying that she doesn't feel loved with her "man". 
She tell me how he still acts like a kid and doesn't help her. She lives with her mother in laws house still. Bc her "man" doesn't feel like they are ready to leave the house yet. But he likes to go out with her. He goes out with his brothers and friends out to have fun. And she home with her baby girl. 
What should a good friend say to her that might break her heart to hear... What advice? I understand I am putting her business out there but help a sister out. 🙏
