So sorry you are going through this, OP. There are lots of decent and savvy women here that can help and support you whatever you do. But life is long, mistakes are permanent. Most of us have learned that the hard way, and want to use that bitter wisdom to help others make better paths.
Certainly keep your baby if that's what you want to do. That should go without saying. But, if so, that decision becomes paramount. Very seriously. It means you will put that life above EVERYTHING else. Including a Temu wide boi. That decision is finite.
At the least, demand space; move home (or out of shared accommodation); prepare to go it alone and after that, if he fights for you both (you already know in your heart if that will happen, sweetheart. That feeling right now, reading that. Whether that knowledge gives you hope or puts a pit in your stomach, you DO know.) he's a good guy. It's not easy, especially for younger males.
Daddy has best part of a year to go through all the stages.. He will, it's right there in his attitude in that screenshot. He will come out the other side a Dad or a biological parent.
Prepare for this baby to change everything you know about love, loyalty, strength... If it changes him the same ways he can be a brilliant dad, it might just take some learning. If not, If you already have your own space and security and boundaries, you will be equipt to make the right choice with no second thoughts or doubts.
I wish you all the best of everything.
