My parents want my EX girlfriend to have an abortion?

I recently found out that my EX girlfriend Aubrey is pregnant. She texted me the news letting me know how excited she is about becoming a mother. She is a stripper and we broke up because i want her to quit stripping but she refused. My parents hate her they think she is nothing but an immoral slut and they were pissed when i told them she was pregnant. They said they couldn't believe i was stupid enough to sleep with her much less impregnate her. They told me i should get tested for an STD. They told me they want her to get an abortion because if she has the child it will ruin my life and our family name and reputation. I don't want that i love Aubrey and though unexpected I'm looking forward to the baby and becoming a father. I'm sick and tired of them treating me like a child I'm a grown man What should i do?
