Ugh, I'm so frustrated 😖

So I've been with my be for 2 years. & I got pregnant. I'm almost 3 months. But ever since we found out I'm pregnant. He's changed so much... He will get mad if I ask him who texted him, or who called him, or why he did this, etc. he erased me from his fb, and his snapchat, & now he blocked me... I asked for his password, cause j feel like something is up, and he gets mad at me, he gave it to me, but then he changed it right away... His phone now has a lock, I know what it is, but it's weird... He has another child with another woman, & when they got pregnant , he posted stuff about it on his page... But with me... He's hiding me.. :( he's blocking me and shit :( & now all of a sudden he decided to pay more attention to his other child. Like buying a lot stuff for her, spending more time with her. And me? Fck me... I don't got feelings. Cause all he does is treat me like shit, hide me, & not even be supportive to me...  I moved out of his house because he has anger issues.. He's called me a piece of shit, dumb bitch & other things... He's done so many mean things to me during this time where I need him the most, that I just cry all the time :( why is he being like this?:( he makes me feel like the bad person when I clearly know, it's him. :( it hurts because we were ttc, and now that I'm finally pregnant, he starts acting like I don't matter :( But yet he still wants me to be with him, when he's hiding me... Like wtf? Seriously.Â
