Should I bother or not reply back?

I'm a (30) M who matched with a 28(F) on Tinder. Our lead-up to the date was great; we texted and agreed on a date. Before I turned up on the date I was late, a guy was chatting her up she told him she was here for a date I caught the last part of the exchange but she was not impressed she had the most pissed of expression on her face was funny 😄 lol
The actual date went well too – lots of kissing, hand-holding, and a message from her saying she got home safely. We've been continuing to talk, but she went quiet for a couple of days due to a family member's illness. We discussed planning our next date, and though we were close to agreeing, she vanished mid-conversation. We tentatively settled on a Wednesday, but I hadn’t heard from her since our last exchange on Monday, then she replied back the day of our date replying to my previous message, and explains about her sick family member, also that she completely forgot that today was the date we planned, I replied back saying hey you had a lot on so completely understandable. Is this situation worth pursuing or should not reply and ghost?
