Pregnancy

Don't Judge Please . 
I am pregnant . 
I'm 18 & my SO is 20 
I don't want an abortion , but he wants to be more ready then he is right now when we have our child . He doesn't want me nor the child struggling . But i think i want the child. I don't have a job & he is a barbor but does that on the side . So we barely have money right now . He is thinking about going to the air force . While i'm pregnant to support me and the child but isn't it true you have to be married  to have people support you when your partner is in the air force . We have both been trying to find a job . It's so hard . my nana would help me alot , and i know his parents will but I'm scared because i don't think he wants it mainly because he doesn't think we can support it financially . Has anyone been in my position (not everything simiar) and have been fine & their child is healthy and has everything it needs ?
