How should I tell my dad?

Ellie
I told my mom as soon as we found out and my husband told his parents too. The only problem is I have a tough relationship with my father and we don't talk often. I feel like it would be awkward to spark up conversation after several months to tell him we're expecting. It doesn't help that the major reason I don't talk to him is that he doesn't like my husband. What would you do?
