I’m not good at this

I have been texting a girl and speaking on the phone and I really like her and I can tell she’s just highly successful and she just launched her own business so I have been asked to please be patient? She told me about a funeral and I forgot and my mind went worst case scenario. Thankfully, I didn’t piss her off with my sarcastic close “I guess you can call me Casper because I have been Ghosted!” I would want to stay in phone contact but I have said I am here when you are ready and now it’s positive texts and it just feels like she is moving away ? Should I just forget about her? It hurts and I am so messed up, I can’t stop thinking about her.
