I 18m found out today that my partner 18f is pregnant and I feel trapped

I think the title really sums it up really but obviously context is needed. We’re both raised religiously specifically Catholic so abortion is not an option unless her life is in danger , when we became sexually active I made it very clear that I’m not ready to be a father and I thought we were on mutual terms. I feel like I’m never heard and she doesn’t care for me despite saying she does e.g after I got back from the gym last night at roughly 1am we were led down for a while but I started getting excruciating head pains and she comforted me throughout and genuinely helped but the second it started fading she asked me to go downstairs to make food for her , when I said I didn’t want to incase the pains started again and I potentially fell down the stairs ( 2 flights) she started screaming and went down grabbed something out the fridge and said “ that wasn’t so hard was it”, I also said I wanted to go to bed but she started watching tiktok on full volume meaning I couldn’t fall asleep, when I asked her to turn it down or put AirPods in she refused so I didn’t get to bed until roughly 5-6am after she fell asleep. This wasn’t just a once off, these sorts of situations occur frequently ( multiple times a week) over very little things. I know I’m not ready to be a father and likewise I know she isn’t ready to be a mother and when I said this she said that she’s keeping it no matter what despite quite literally everyone she told telling her to abort it. She’s currently looking for a job ( has been for about 2-3 months) with no luck , she dropped out of college so has no education and obviously can’t go to college pregnant for many reasons, I’m going into the army next month doing an apprenticeship so I won’t be home a lot so she’d really be on her own. Obviously there’s the issue of finances, after speaking to a lot of people myself I’ve been told the same thing over and over; people won’t hire pregnant women, I’ll be making decent money but all of it will be going into savings ( ISA account) so it won’t be accessible and nothing will change my mind about that ( I’d rather be able to live well in 15yrs time then have flashy stuff now , if I had access to the money it would be spent the minute it dropped in my account so this way it’s extra money+ I can’t access it whenever), really she’d be relying on family, yes the support will be there’s only so much people can do with the economy being fucked 🤷‍♂️

I’m not really sure what I want to be answered but if anyone thinks of any sort of advice or what have you it will be greatly appreciated.

Thank you
