And I can't speak for your relationship specifically, but if you're doing everything you can to make rent and you have a good partner, you're not gonna get dumped. Will they maybe be frustrated with the situation? Sure, finances in a relationship are a huge stressor, but a good partner is going to emotionally support you through this as long as you're doing your part. You're posting on here looking for work and assistance, which shows that you are. You're not expecting them to just fix everything while you do nothing, you're just stuck between a rock and a hard place financially between school, rent, and just surviving. I'm sure your partner will understand. And if they don't? Then maybe getting dumped is for the best.
Idk, I've been in similar situations before, more often than not my partner understood. And when they didn't and ended up leaving me, my life got better for it, yk? Best of luck friend.
