Why would this guy lead me on and lie about having a girlfriend then block me and turn around pressing charges on me?

i tried to reach out to him, he keep blocking me. I found out i was pregnant. I told him before things turn left that im missing my period. I have reached out to people who may know him to let them know i'm pregnant and thats when i found out he had other girlfriend. He never claim he had a girlfriend but the girl claim he was his girlfriend and he had another girlfriend he been with for 15 years. I thought i was the only one. He lied to me. He now threaten to press charges on me for telling the girl ''his business'' with the truth and that i'm pregnant with child. He denying the child at first but then he turning around saying i should get rid of baby and i told him no and i haven't heard from him since. Why is he doing this to me? i'm pregnant and I'm hurt, angry and I'm scared because he might be trying to put me to jail to silence me. before everything went left, I told him to give me money to buy plan b just in case i get pregnant, I had no job at that time to afford it i had just came from staying in another city at that time. He told me he didn't have the money but i saw him posting on his instagram story that he brought $200 shoes. I'm hurt and angry and he's probaly use text messeging against me as harassment because ''I'm putting his business in the street''... little did he know its my business too. right now he's not blocking me no more, he's ignoring me... I send him pictures of ultrasound and pregnancy test to prove to him and thats the last text. I'm blaming myself for putting myself in this situation... he lead me on. I'm hurt because he's running off to the sunset with this girl and he probaly telling her lies , she was nice to me at first but when she told me he said to get rid of the baby and i said no... she blocked me. Please excuse my grammer and spelling, I can't think straight and i'm typing fast.
