Is this girl interested still? What's her deal?

[MusicMan81]

I met this girl online about 5 months and we talked almost every day via text or phone calls. We really hit it off and she would always say how much she liked me, even tried to help me with my resume, and we just really got along well. We met a few times after the 5 months and had a blast, and she even came to my house for dinner. She would always say that she cares about me so much, that she misses me, and has feelings for me. About a 6 weeks ago her grandma got sick, passed away and she said she had a lot of family problems she had to deal with. I never hear from her, when i text her she hardly responds and when she does she says "i'm so overwhelmed with all that's happening with my family" and "I can't give time to see you right now cuz of my family issues". It's crazy and it's getting worse BUT for some reason when i ask her questions like "do you have feelings for me? or do you care about me? She replies with stuff like "I do i'm just overwhelmed with other stuff right now" and "i think about you a lot and care about you too but i have so much going on right now". Why is she so overwhelmed? I call her and leave her messages to cheer her up. One time I even asked if i could keep texting her and she said "keep texting i like hearing from you" yet i almost never get a response from her. She does say she's interested in so many words when she does respond. I'm just so confused as to why she keeps telling me she's overwhelmed. This has been going on for 6 weeks now! I need your help. Serious answers please. Thank you.
