If he says he should get a say about a termination, he's wrong. It's your body. He had 'his say' when he didn't use a condom. Your body, your decision
How do you know that he didn't use a condom?
Not sure if you're still reading OP?
I think that both people should have a say, providing it was a genuine accident (i.e. you were on the pill but were one of the 1 in 100 who got pregnant on it, or he WAS wearing a condom but it split). That's not to say he should have the right to march you down there and demand you get a termination, but he has the right for his side of the story and for his feelings to be heard, just as you do yours.
I don't think it's as cut and dry as this "It's your body, you do what you want and don't think about his feelings!" stuff. It's his life and baby too. Do you want a relationship with this person longterm? Is he a good sort or a bit of an unreliable one?
Abortion is hard, but so is raising a child, more so if you're going to be doing it alone. Do you have support around you? Enough money to live on for you and a baby, plus bills, car, food etc.?
