Extremely Hurt! 😒

So I have been dating this man from my job for about 5 months now when I recently found out I'm 8 weeks pregnant & was told to abort from him but honestly I'm against doing it all my life ! I told him I was keeping it & his response was disgusting! My family is supporting me 100% & im going to be a happy single mother! Not sure if to sign this letter or not? I need help 😥
