Scared , is abortion the answer? ?

My gf jus found out shes pregnant last week. We talked some an I Jus figured we'd keep.the child. Then she brought up that we don't have to do this. I've nvr thought of abortion. I think it has its place in situations. But I think we can have it even tho ik it'll be hard. I'm on the fences. I'm outta college so I'm ok.with it I guess an the thought of having a child is starting to grow on me. but she Jus started in the fall an has to be on campus the next 3 years. I understand her not wanting to keep it, even tho Shes not sure. ik that's what she's leaning towards. The thought of abortion makes me sick :/ but if she ends up wanting that then I can stop her. Never been so scared in my life. I really do think I wanna keep it tho. My concern is my girlfriend. She wants her goals an her future before a child an.I understand that. I'm not sure if we're ready for this. But Idk. She thinks she's not gonna be around much cuz of college an that's probably true. She wants to be there for her child. An not have to worry about it til school is done. Like I said I'm outta college, did plan on going for something else in the fall. But that's not a must. I make $16/hr which Idnt think is too bad. But could I support a family on that? I've always been taught to do the responsible thing an if I got in this situation I'd keep the baby. But now Idk what the responsible thing to do. Keep the baby an bring it into this world not the way we planned an struggle or wait an do it right down the road. Honestly I'm.Jus worried she won't do what she wants with her college major an goals. But I heard maybe an abortion could mess up the chances getting pregnant down the road? Ik some family members would be upset bout the idea of us having a baby but they'd come round an ik they'd help. But if we got an abortion I could nvr tell them, I'd feel too ashamed. She Jus wants to be there an sounds like w college its gonna be hard Idk if I'm ready to be a dad or not but ill step up to it. Advice?
