What would you do?

Hi I'm a single mom to a beautiful 4 year old girl, I'm currently unemployed and I'm living at my mother's house. I am single but I do however have a sexual partner, we aren't together it's more of a friend's with benefits relationship. Well I'm pregnant for the 2nd time and now I'm a bit confused on what my next step should be. He doesn't know yet and I am planning on telling him tomorrow. As far as the new baby goes, I've never been ok with abortion but I also don't agree with bringing a baby into this world to automatically be struggling. I've also thought of an open adoption but I just don't know how well that would go considering this is my 2nd child. I've always wanted another child but now just doesn't feel like the right time, I would love more than anything to keep this baby. I just don't know if that's the best decision right now especially considering I'm unemployed and living at my mother's. I just would like to know your opinion and what you would do in my shoes. Thank you
