I need help plz

I just can’t deal with the shit going on in my life anymore. Tonight has caused a lot of havoc in my life and I’m just emotionless. Currently I’m going thru a hard time. Someone has gotten a hold of my ssn and has tried taking out multiple loans online. I’m literally at a point of no return which honestly has taken a toll on me big time. I broke up with my bf tonight. Honestly I don’t know what to think anymore. This person who is doing this to me seemed to be someone I thought I knew, however it didn’t end up being her. I tracked the IP address and it was out on the west coast. Since I thought it was this girl my ex took my phone and called her started yelling/cussing her out. She assured him it wasn’t her but as she was yelling back at him she called him names so once he got off the phone with her he got mad at me bc I didn’t defend him. I had no time to even say shit bc they was going at it back and forth. I know I’m not perfect and things could’ve gone differently but the fact is they didn’t. I’m just over here dealing with all this shit in my head and all I can think about is I need to stay strong for my child. My child needs a functional mother. I’m stuck with this guy anyways. He just went off on me before I ended things with him and said he isn’t marrying me until my credit shit is in order. I told him my credit or your credit has nothing to do with each other. We are both unhappy in this relationship. I can’t seem to ever get him to understand it’s not working out and how miserable we both are. There’s literally nothing I can do right for him and I’m just sick of it. He’s tired of dealing with my problems and I’m tired of him causing me chaos and stress in my life. He walked in the room as I’m writing this bc who else can I vent too? He says i come on here and trash talk him and went off on me again. I’m not trash talking anyone. All I’m doing is venting bc sharing anything with him just gives him a heart attack. Honestly there has to be a way I can get him to fully understand and remember everyday that things are not working out for us. He doesn’t seem to fully understand so if any of you have any advice for me to explain to him in the nicest way possible that it’s a dead end for the both of us that would be great. And like I said, I know I’m not a perfect person but something has got to give. Once he cools down things won’t be cooled down for me bc I truly know in my heart that this relationship is over. I need him to understand bc I’m going to continue living with him raising our child.
