OP you could break up with him at some point. Many relationships don't last. Don't have an abortion to please him. Being emotional doesn't mean you're incapable of making decisions, deciding what you want or making a less than ideal situation work.
He had the means to prevent this pregnancy occurring if it was that important to him not to father a child. He could have used a condom, had a vasectomy or abstained from sex. He chose not to. If he feels his life is ruined by you having a child, he needs to remember that he was the one who ruined it (and then grow the fuck up and stop being so dramatic. Men can and do walk away from unwanted children and it has zero effects on the man's life (lots don't pay child support), except that he can't continue having sex with the mother of his child who is now his ex).
He's not being logical and reasonable because he's not taking into account the fact that you want this baby. He's a gaslighting arsehole who is trying to convince you he's right and you should ignore your own feelings.
You need to consider things like how you'll feel if you have an abortion and something goes wrong that means you can't have any more children. As well as the guilt you may feel over this one, which has the potential to destroy your mental health and so your life.
I'm pro-choice. Women's choice. About what they do with their own bodies and lives.
I hate how men think contraception is a kind of optional extra that doesn't apply to them/isn't their responsibility, that an accidental pregnancy isn't the end of the world because there's always abortion as an option to reset the situation.
If you don't want an abortion and have one because it's what he wants, there's a high chance you'll end up resenting him and breaking up anyway. You'll be grieving and he won't be able to support you because he's not grieving with you and is instead the cause of the grief. Meanwhile he'll be breathing a sigh of relief and expecting things to return to normal ASAP probably thinking of abortion as no big deal for you, because that's how it feels for him.
So the only question is: what's right for you (and the baby)? Leave him out of the equation. Look at all your options for your degree. Like deferring or crèche. Talk to them about what options and help there are for single mothers at the university. There's probably a counsellor, speak to them. Speak to family planning counsellor too. Think about how having the baby impacts your life and career. Think about possibilities for how to manage your mental health/life if you have an abortion, it's a life changing thing. Some people can put it in the past fairly quickly, the ones who knew it's the right decision for them I expect, it's probably not that easy for the ones who were talked into it, but some people need time and help to get over it. Decide what's right for you, whether that's having the baby and keeping it, having it and putting it up for adoption or having an abortion.
Then see where his place in all this is, which isn't solely his decision either, unless he breaks up with you and walks away from the child completely. If he wants to stay together and you don't, you can tell him to get lost. If you have the baby and he wants to see the child he can discuss that with you, he doesn't just get to decide when. I'm mentioning this because you're maybe used to going along with what he wants and don't realise the power you have over your own life and future, both the big decisions and the smaller day to day ones. You mentioned respecting him. This decision about the pregnancy has nothing to do with respecting him or not. You can respect someone whilst also not agreeing with them and not doing what they want.
Good luck.
