AITAH for not wanting to keep my child

This is extremely serious and I am looking for honest advice. I know this is a delicate subject matter so I want to thank everyone in advance for their opinions.

My (19M) gf (27 f) is pregnant and I feel like she took advantage of me.

I don't want kids and she does. there is an age gap so I feel like that is contributing to her decision in wanting them. I dont want her to keep the baby but she says I don't get a choice in the matter since im a guy. I feel like this is unfair and I feel so trapped. She said that I have to pay everything while she quits her job? I know that this is the right thing to do but I just feel so trapped. I've always been against certain ways of taking care of this kind of thing, but I'm starting to think that this isn't fair to guys. my dad and mom say suck it up this is just the way that it is and I'm acting irrisponsible and not as a parent should, but I feel like I should have more choice in the matter. I've been told that I made my choice when I had sex, but I have been very vocal about not wanting kids ever even since day one.

I’m usually very careful as well when it comes to preventing pregnancy, but I do understand that accidents happen. This just feels like I’m having all my rights stripped away, and if I ever did come around to children I wanted it to be on my own terms so I can be the best dad ever. Even with that I’m not sure that I’ll ever want kids anyway.

TLDR: am I the asshole for wanting her to end the pregnancy since I’ve always said I don’t want children?
