Does she still love me/?

[Chrome]

I need some really sensitive and understanding people to help me if your reading this please answer, I would really appreciate it. Me and my girlfriend are fifteen (please don't complain about the age). She's in a wheelchair and has epilepsy but she means the world to me, she is the person I want to be with. She asked me out last week after a period of close friendship. She seemed distant near the end of Friday and yesterday so I asked her on twitter today if she needs space. She said she needs time with her dad (they have a complicated relationship).

I was relieved I thought I knew where the strangeness was coming from. I messaged her goodnight yesterday and she ignored it like she did Friday night. I get that she needs time with her dad, but why should that stop her from replying when she was using twitter anyway? At that made me so angry and upset. I knew she was online but she ignores my message (she usually always responds when I say goodnight). If she had messaged me I'd have replied instantly yet she just ignores it. I don't feel like she cares about me anymore and she was fangirling about her faviroute idol (a rock star) tweeting him and everything.

I understand she needs space, she's going swimming with her dad today in fact. But does she still love me? When she told me she needed time she said "sorry x", which gave me some hope.
When I say she asked me out last week, I meant she asked me if I would be her boyfriend. We had been saying earlier this week that we love eachother.
