I'm sorry to hear all this, that is a rotten situation.
If you need support and advice, that's what this site is for,

! We're here to help you and back you in your decision. Like I've always said, it's your body, you do with it what you will. Don't let anyone else tell you otherwise.
Talk to your boyfriend about this. Find a time when your both relaxed, or go somewhere peaceful and relaxing for him. As I always said, it takes two to tango, so he's as equally responsible in this as you. You TRIED to stay safe. You may be right that God is sending you what He believes is in your best interest. I've heard a lot of people say "God will not hand you anything you can not handle" This might be true! Consider your options.
As far as not getting support from the people closest to you, well, I guess they aren't the best of the closest? You don't have to talk to his parents. And ask your boyfriend if he thinks he's ready to be a father, not his family. Have a serious talk about it. Just relax, and take it as it comes.
My best advice is that if you want to keep your child, then keep it! Even if he wants no part in it, there are state programs and stuff in mostly every state to help single mothers, especially if you're at a young age. And if he wants no part in your child's life, forget him, there's much better men out there
