I've been chatting to a girl recently over the last few months - we enjoyed chatting during lockdown and things got a bit sexual. We've spoken a bit less in the last few weeks due to my own personal mental health issues and I took a few weeks to sort myself out. Now I feel like having something with this girl, seeing her a few times perhaps. We were texting the other day and things seemed ok. Yesterday, 24 hours passed and she hadn't even opened my message yet she had been online a lot. so i sent another couple of messages, one starting a conversation and one asking if things were ok. i get the message literally one minute later "Jesus, I'm busy, leave it out" to which I said that's fine, just let me know would be nice (we are not mind readers after all) to which I get a very sarcy "normally when people don't reply it means they're busy".
I haven't replied and I don't know what to do next. I'm almost sitting here waiting for a nice message from her. Do I apologise? Do I message in a few days? I don't want to be a mug because she's been a bit nasty but where do I go from here? I do really like her and we've had a lot of chemistry before this but she does have a bit of a tendency to go hot and cold. She was so interested before which really confuses me.
