Stuck

An

So I recently found out I'm pregnant by my ex boyfriend. Me and him are on good terms, but I don't want to keep the baby and he does. He's really hurting and has turned to drinking and smoking more often, but I don't get mad because I know he's been waiting for this for so long. In his past relationship, he dealt with his ex having an abortion and a miscarriage. During our time together we had 2 miscarriages. This time was unplanned and after our break up, I just realized having a kid right now isn't right. I have no job, no working car and still live at home. He does have a good paying job but has no car and still living with me and my mom's. I feel like we wouldn't be able to provide for this baby and there's so many negative outcomes than positive. But he keeps trying to get me to change my mind to keep it. I feel so bad as it is to face this decision, but I feel like it's what's best because we need to focus on bettering ourselves and getting somewhere in life. We are struggling to manage now and to bring a baby into this world under the circumstances is crazy to me. I know there's adoption as an option, but I don't want to go through this pregnancy at all because I know I'll soon get attached. I don't know what to feel or what to do!? My emotions are all over the place and I over think everything! I have set my appointment for the abortion but mainly to talk about options and decide if I actually want to go through with it. I'm pretty sure I want to go through the process just because I know I can't provide for this child. He can up and leave at any point and time where I'll be left with nothing. Any advice out there?
