I know how you feel. I was with my sons father for over 3 years, once I got pregnant he wanted me to abort my baby or he would break up with me well I chose to break up and when I was 8 months pregnant we broke up.. He never signed the birth cert. and my son has my last name, However I do let Aidens fathers mom see Aiden and he is aloud if he wants to, even though he barely does spend anytime with him. Take your ex to court for custody, get child support( he cant spend all his money on beer if he has to pay for his child and if he doesnt pay he goes to jail) You will never regret being a mother. My son is 3 yrs old now and I dont make much money at all but I live with my parents and that helps alot until I really get on my feet with being a young single mom. I admit its hard sometimes and I still want to cry sometimes but I know it will get easier and I love watching him grow to an amazing little boy. Also I forgot to add you can go to court to let his father get visitation rights but you can be with the baby when he see's the baby that way he is supervised at all times.
