I need some help

First I would appreciate if no negative comments were said. Im human and have struggles as you and if you don’t have any positive or beneficial words then I don’t want them at all.

I just found out that I am pregnant with my second child who will be 2. I am not with her father and he is not in her life. I had moved out when I had her and had a job and a car and really had everything together but had to move back with my mom after we broke up and now I can’t decide what I need to do. I don’t think the guy I am with is ready to have a child and doesn’t really seem there for me at all. (We’ve only known each other for a month btw)I am fine with raising another baby alone as I know I have the strength and mindset to do so but I don’t know what to do if he comes back later and wants to try and take care of it. Im very protective and very set about how my children are raised as I have dedicated my life into making sure I’m not just doing minimal for my first and for any future kids. I have a set way I believe my children should be brought up and I just don’t think I can trust someone I just met to take care of a kid ALONE that I just held for 9 months. I need to know if I’m overthinking or if I have reason to feel like I would rather do it alone. This is just a small portion of my issues in my head but this is all I could get out. Could I please get some comments on how to maybe help me through this hard decision
