So.
> I fucked up her entire life
You didn't. It's not clear if she asked you before or asked but ignored you but she wronged you. She made a decision and it had consequences. As I previously said maybe you overreacted a bit but that's done now this is the hand you dealt for yourself and you have to play that. Nevertheless she either didn't know you enough or didn't care back then, she thought she can live with the consequences but she can't apparently. It is also not your fault that her parents are like that. I'm not saying here you shouldn't feel bad about your behaviour but I'm not saying you should either.
Now, judging by what you wrote I believe you can together if you want it even if she doesn't or won't say it. However you should know that building a relationship on you feeling sorry for her and having remorse is not a good idea and these will torpedo the relationship in a different way. If you actually have feelings for her and/or you judge she is a good material for that, then go for it. Spend some time together, give her a pleasant experience and do what you have to do.
However. If you do pursue that course, it is important to send the correct message. She might get the wrong idea that she managed to manipulate you back into the relationship, so it was her decision that made it "right", you were in the wrong and she made you see it.
No. She have to understand that she wronged you and despite this you can get over it and give her help and comfort by your own decision. Not because you are feeling guilty, but because that's the right thing despite what she'd done. Ofc, this have to be done in a way you don't look like a dick while you do it. Basically she has to learn it that you are in control and not her and if she let herself guiding you and not fighting you everything will be a-ok. Ofc this is responsibility and you shouldn't abuse her trust and this is a long time commitment.
