First, if it is an ectopic pregnancy you will need to abort or your life would be in danger.
But, if it is a healthy baby, it shouldn't just be "his" decision. You are part of this and you both need to discuss it. Are you married or in a long term relationship with "him?" You can always do it on your own.
I'm sorry you're being put in this position. If "he" wants to play he needs to know the risks of pregnancy occuring. He doesn't sound like much of a man from what I'm reading.
