Getting pregnant by your best friend whose also your ex? Yay or nay?

So I slept with my best friend who is my ex and I know it wasn't smart to have unprotected sex. Yet we both aren't getting any younger. We're both about to have birthdays soon and reaching close to that 35 mark. I wonder if it's a good idea to have the baby if I do become preggers or abort the baby (with his consent of course).

I'm not really for an abortion but I'm also not for having a baby without being married. It's a sticky situation but I think I will choose to have the baby if it comes to pass.
