IUpdate: baby daddy issues please give as much advice as possible.. I nedd it

The man i was in a relatioship broke up with me shortly after we found out that im pregnant. Havent been on birth control in over a year, he knew & we obviously werent doing anything to prevent a baby.. Anyways I never met his family & he's never met mine. I want my daughter to know the other side of her family but he's made it clear that he wants no part in our babys life. Im hurt , but im not dwelling on it bc i have to step up and be both mommy and daddy. My due date is 5 weeks away and his family has no clue about my daughter. His cousin that i went to school with sent me a friend request on facebook & i feel that i need to tell her everything so she can tell his family. I don't want my daughter to be kept a secret. Idk if i should just keep things the way they are now or try to have his family in her life . i keep thinking that his family wont believe me or he'll try to cover it up w/ his lies. Im so lost .

UPDATE: I spoke with his cousin and it turns out rhat his family knows & has known for a couple months. Im beyond hurt bc they obviously want no part in my daughters life. My baby girl already means so much to me & her father and his family don't care at all. Guess ill just figure out this whole mom thing as i go .
