Adoption or no?

So here I am going to try and make this short I started dating my girlfriend for a year now. When she first met me on Facebook for 3 years. I had to move in with her and her famy because they lived 40 miles away from me and me and my girlfriend didn't drive. It turned out her mom was crazy and so was my girlfriend. He mom was a lesbian mom in her 60s that adopted my girlfriend at age 12. My girlfriend has disability's and went through a lot in her live getting malested and all by her biological family. Before I moved in the two mothers separated because the one became a jahovvas witness. Well this other one was controlling and wanted money etc me and my girlfriend moved back to my hometown. Well little did I know I made a stupid decision and got her pregnant possibility. Here's another thing. My girlfriend isn't capable of holding a job. But she flirts with like hundreds of bad guys and she even cheated on me and everything. She's very messed up. To this day I still gave her this one chance because I fell in love with her. But she's crazy in her own way and so is her mom. Everyone thinks in her family and my family the baby should be adopted. Both of our familys now hate each other but me her and her mom are trying to work out where we can make this work and keep the baby so we can raise it and my girlfriend seems to be doing good but there's conflict between her and her mom. I'm taking a risk moving back uo there. I love this baby and there's no way for me to be able to.keep in it the situation I'm in because I live with my mom have no money and I just am recovering getting hit by a car. The sad part is I don't know if the baby is mine yet but I can wither go back to my old job and stay in my hometown and not take a chance or go back uo with them and take this chance because there's nothing more then I want for this baby to grow up with her dad and I am and my girlfriend is positive its mine because we were at my mother's apparently by the time she got pregnant unless if it was when she left somehow but she was with me a lot at that time so idk
