In need of advice not judgement I’m pregnant

So I found out I’m about 4 weeks pregnant I just turned 19 last month which is when i also got pregnant I was in shocked I recently got off birth control for other reasons in June I been in a relationship for a little over a year now with my partner and he is 24 I told him I was off the pill that we needed to be cautious and use condoms pull out etc he was fine with that but once we started having sex we both became careless not thinking of the consequences of our actions now and I’m so stressed I have no idea what to do now I still live at home with my mom I don’t even know how to drive I do have a steady job and haven’t even applied for college yet but if I keep this baby I’m determined when this baby comes I’ll be in college doing classes online and working and know how to drive and my mom has already told me she’ll help me learn and buy my own car now for my boyfriend he knows how to drive doesn’t have his own car will be getting one he says he is living with his is mom temporarily now ( 7 hours away from me ) and is looking into buy a house ( about an hour away from me ) with his close friend / roommate and does have a job but always finds a new one it’s clear we aren’t ready he knows I’m pregnant and told me the decision is mine and I just don’t want to make the wrong one also he told him it makes sense not to keep it and I told him I agreed but now I’m unsure if I could forgive myself for getting a abortion or adoption and even if I actually have the guts to go through with it and on top of that last month I found out he was talking to some girl online for months on and off flirty and I’m still forgiving him for that I haven’t told anyone not even my own mother my cousin just found out she is pregnant also not ready and they shamed her and talk shit but still support her even though she isn’t ready and my mom told me not to make the same mistake and I did ... I have no idea what I should do or whether I should keep this baby or not I’m so sick haven’t talked to anyone besides him and I’m super stressed my hair is falling out I can’t even think I don’t even know if I can handle an abortion or adoption mentally please give me some guidance thank you in advance please don’t judge me I’m already disappointed in myself
