You can post in here to find other single and pregnant mums to share your journey with too! Or maybe even get some advice from those of us that have been-there, done-that!
It is absolutely incredible that this couple sat down together and decided all by themselves to get you pregnant. That shows a lack of boundaries and disrespect for your right to decide whether you wanted a baby with them.
They decided to "help you out", that is absurd - the father would have been 50% responsible. I have no idea what is going on with these people, but they already have enough kids to feed and clothe. It is also mind boggling that they have kids and one wonders what their ages are. I certainly wouldn't want my developing child in a household where they come home with questions about these sorts of activities going on.
The guy really should stop breeding, and shows more about his need to breed than any concerns for you. 8 kids! and I'm sure all those kids emotional and physical needs are met my this guy. Some men should be castrated after they've "fathered" a certain number of children. If I were you I'd be getting tested for venereal diseases pronto.
