I fingered my girlfriend, she hates me & her mum has cancer HELP?

Exactly one month ago my girlfriend called me over to her house, the night ended with me fingering her and her masturbation me at around the same time. I left with a long kiss, now the day later and all the days after that she i ignored all of my texts and my messages, I asked her friend to find out what's going on, she came back to me saying that she doesn't want to speak to me. Fair enough. So I gave her space now 12 days went by after the incident, and she began texting me asking me to reply to her texts ( I wasn't replying ) after another 4 days I got a message asking what I was doing and where I have been, with moody and short responses I answered her questions she eventually asked can we be friends? Now I was shocked, and i think it was mostly because she feels guilty and regretful for what she did as do I ( virgin regret ). Hurt I said no I don't want to be your friend, because I see you as a girlfriend and things would only complicate that so I suppose we should move on in different directions. At first she said 'no please :(' she really didn't want that. But I was persistent and said 'no' eventually she said fine delete me and then I'll delete you, I said no if your going to delete me go ahead it won't make a difference if I do or don't. she replied it does because then I will add you back ( she will be tempted :/ I think ) and I said no you won't dw. This is when I told her I had to go, I came back the next morning and she had blocked and deleted me :(, it's been two weeks nearly and I've been blocked and deleted, I've also found out her mum has cancer just recently and this was around when the time when she asked to be friends. Right now everytime her friend mentions me to her she gets angry, hmm I really need your advice, I feel sick and horrible and I don't want to be her friend I want to so much more than that, help
