<human>: Hey guys. My question is pretty much that in the title. He and my mom divorced when I was 4. He lives across the country and we don't really talk. 

I learned a few years ago the reason they got divorced is because he was into meth. He did meth for 15+ years, stopped and then became a alcoholic. 

When I had my first son him and his wife came to visit and they were drunk the whole time it was awful. 

They sobered up and he came to my wedding two years ago alone and that was great. I thought that would change everything but he never called me or anything. His wife would text me on my birthday but it was all about her. From what I can tell they have been completely self obsessed. I haven't talked to either of them since the wedding. 

Now I'm pregnant again and my family is pressuring me to tell him. They say he loves me just made the wrong choices and that he will find out somehow so I should be the one to tell him. 

I was thinking if I do I might just text him. Even thought that seems awful I just feel like I don't owe him anything. So should I tell him and if so how do I tell him?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My dad and I haven't talked in two years and don't have a relationship. The rest of my family  thinks I need to tell him I'm pregnant but I'm not sure if I should or how.
