Rose Jam sounds good. It also sounds good even though I don't like eating roses...lol

It sounds like you should be talking to her about it, maybe after finals but tell her how you're feeling and how you want to stay committed and how you do care and just want some assurance that she does too. And then maybe the hardship doesn't feel one sided but is something you share and fix together. But again, if you feel obligated due to the past, to stay, it might not be healthy. But that's something you need to decide together.
