<human>: Give me the gist of the text in a nutshell

I'm currently 19. My birth parents had me when they were 19, in college. Gave me up for adoption, it was closed. I found some medical records with some identifying info, did some research, and found my bio dad on Facebook (I had no info on my birth mom).

I contacted him, telling him I would love to talk. I didn't say anything about meeting (although I'd love to meet him), I just said I'd love to know what he's like. He replied saying he can't let his wife and 2 kids know about me, and can't have any sort of relationship with me. Said he doesn't really know why I'm contacting him, said he was in shock. Also said he'd contact me after he thought things through, but it's been days and I have no faith that he'll actually contact me again.

How do I cope with this? I never had a good relationship with my adoptive family. I have no family, no siblings, no grandparents, etc. But I just found out I have 2 half siblings on my dad's side, and I'm not even allowed to see or contact them because my dad wants to keep me a secret. They're young, and I would love to be in their lives. He only lives 20 minutes away from me. All I've ever wanted was to know my birth parents. I searched for years, only to be rejected.

My whole life I wanted to talk to him and my birth mother, and he's completely rejecting me from his life. Any advice?
