@Justmehere That was why I liked him -- because for the first time I was with the "nice guy" and not the "bad guy." I guess that's why I feel like I somehow turned the nice guy into a bad guy ....
I totally hear ya. Exactly what you describe is super common. Most predators are not going to show signs of it at first. They often seem like the nice guy. I've been through it myself. I finally thought this guy would be the nice one and he ended up assaulting me one day. I wasn't super attracted either, so I thought I was picking better guys. I was picking better guys in the sense that he didn't hurt me as badly as previous guys.
It made me feel so damaged. Once I got lots of time and space from it, and I got input from outside friends, o began to see all the red flags I missed all over the place.
In the end, there are not always red flags, the worst predators often have learned how to hide it for just long enough.
Almost no one just suddenly goes from great guy to complete abusive asshole. You two did break up before you were pregnant right? So there was already something going ary in the relationship. Frankly, there are several things you have mentioned that he did before he became violent that are actually big red flags, once that you kinda began to see and teased him about. For example, the crowd he hung out with. Good guys would not seek out to have social interaction with the people he was. They wouldn't get so caught up in that drama and even you thought his behavior was regressive. Pointing that out to him, while you did it in a joking way, was actually hitting on the truth. Which is part of why he got so defensive. If it wasn't true at all and he was making great choices in life, he wouldn't have lost his shit the way he did when you called him out on it.
We also have to keep in mind he is engaged in crazy making and gas lighting you right now and that alone makes any victim of it feel like everything is their fault.
He wants you to believe you made him do this. That's what he is trying to get you to do. It's wrong. It's a load of crap and false.
This is your opportunity to declare for yourself that you do not agree with your abuser, with the way violent abusers view the world and you, because you are not one of them.
No matter how much he tries to make you out to be at fault here for what he is doing, you do not deserve it and it's still not your fault.
Another way to look at this is to understand the power we have as humans. You are not so powerful as to turn other people into monsters. You are not in control of what he does. If you had the power to turn people into monsters I am sure you would instead use that to turn people into good people - but you or I or anyone else can't do that. No one is so powerful to do that.
But what you do have power over is choosing to not agree with him and take in his thoughts and messages to you as truth and as your own.
I know he is spreading vicious rumors and lies about you. Don't start believing them. Live above them. In time, people will figure out that you are not who the violent abuser says he is, and if they don't, then they were crap people anyhow.
You have a new life coming into the world and it's time to find good people who can help support you on this journey into motherhood. The fact that he may no financially support the child may be a blessing in disguise because then it may been you don't have to maintain constant contact with this jerk.
