Found out friend (F20) that I’ve (M22) become romantically closer with has ovarian cancer?

Got dumped by my girlfriend of a year in December. Struggled the first few weeks, but my focus on mental health recently (over last 2 years) has made this breakup much easier than others.

Anyway, I’ve known this girl for about 18 months now, and for the last 2 weeks, we’ve been semi flirting and having great times when we’re together. Never really hung out until mid January too. Just last night, we watched movies until 4 am, just cuddling the entire night before she slept at my place. We woke up and I made each other breakfast. We spent the entire day together, as she’s kinda sick, doing the same thing as the night prior.

I found out that the reason for her fatigue and cold is likely because she has stage 2 ovarian cancer. She wasn’t the person who told me that either, and i don’t really know what to say about that.

Anyway, I have never felt more infatuated in a person than I do now. Her laugh warms my heart, her hands make me feel connected, humor to make me wheeze, and beautiful, welcoming eyes that seem to truly see me. I was cuddling with her and feeling completely in the moment, an experience that is often fleeting and rare for me. I could really feel the endorphins rushing through my veins. And this time, it wasn’t in a lustful manner. I suddenly had this overwhelming desire just to be there and comforting - not that I didn’t want to have sex (nor do I think it is possible given her illness), but that it wasn’t on my mind at all. For the first time in a while, I was at peace.

I just don’t know what to do. I don't know how we’re go from not spending practically any time together to spending nearly 24 hours straight together. I want to take things slow and be as communicative and supporting as possible, but I am generally introverted and non-assertive. Any advice would be appreciated.

This is also a half rant to get my thoughts out.
