My boyfriend told me he got a girl pregnant and I want to leave, but our family says we should stay together.

I am 19 and my boyfriend is 19. We have been together for two years. I thought my boyfriend was a virgin before we met. That's what he told me. I was a virgin when we met too. <br><br>2 months ago my boyfriends old friend reached out to me on social media. She told me she dated him in high school. She asked me if I had been tested for STD's recently. When I asked why she told me she has genital warts because she dated my boyfriend in 2020. <br><br>I confronted my boyfriend about it. He told me he was a virgin in high school and he never dated or hooked up with this girl. He said she is trying to ruin his life because he rejected her. He said he blocked her number a long time ago. I believed him. <br><br>But then yesterday he came to my house and told me he lied. He said he wasn't a virgin when we first met. He said he dated this girl in 2020 and they were sexually active. He said she gave him warts but he got treatment and he is fine now. I asked if I need to be tested for anything. He said he hopes I'm fine. He said he was going to tell me the truth but he was too scared. I told him I was done with him and he could leave. He left without arguing. <br><br>Then an hour later I got a call from this same girl again. She told me she is 4 months pregnant. She said she found out she was pregnant and when she called my boyfriend to tell him he blocked her number. She told me she was going to get an abortion but then she decided not to. She said she wants 500,000 dollars from my boyfriend or she will go to his family and tell them that he is the father of her child. She threatened to tell them she has an STD and gave it to him if I don't give her the money. <br><br>I did not tell her if I was going to give her the money or not. I told her I need time to think. I hung up the phone and called my boyfriend. I told him what she said and asked if it's true. He said it's true. He said he didn't know she was pregnant. <br><br>I was so angry I hung up the phone. I asked my parents for advice. They said we have been together for 2 years and we should stay together. They said everyone makes mistakes. They told me to pay her off and stay with my boyfriend. They said she is lying about being pregnant but if she's not, then it's better to pay her off than for the whole family to find out. <br><br>I don't know if I should give her the money and stay with my boyfriend or leave him. The whole thing makes me feel sick. <br><br>**TL;DR! My boyfriends old hookup is pregnant with his kid and wants money or she will tell our family we both have an STD!**
