baby daddy problems

I'm 8 weeks pregnant & me and my baby's father are 19. I already had a job, car, and common sense before my unexpected pregnancy. He so much lacked all these due to his past. Anywho, we've been rocky for weeks now even before finding out about the 👶🏽 because I realized we were simply two different ppl who had different perspectives in life. His side of the family thinks he's not ready to be a father and always throw up abortion as my top option, but before getting pregnant I could never picture myself just killing my baby (considering I also suffer from pcos) so I knew this was a miracle baby. I want him to actually try and to do better not just for himself but for our unborn child, but he just shows no interest in getting on his feet. It's really annoying because before when I tried to help motivate, him not knowing he needs psychological help, he used to say if he had a baby he would change , BUT hes still the same!! He even told me "I'm still trying to live my life like I have no kids yet" how selfish right? I been changed that mindset since day 1. He rather spend everyday with friends and smoking than to be here for me and get his sh!t together. Idk if it's the hormones or if he's "scared" but something gots to give. He has a long way to go and do do I, but he has a even longer way at the pace he's moving. At this point I just literally blocked him out my life and changed numbers. Should I keep it this way or just be patient? 😕
