How do I Interpret my crush's response?

Hi all. So, there is a girl I've been texting back with for 6 to 7 weeks, started on Twitter then went to IG. Recently, we met up on a date for the first time but I kept it very PG 13, very polite, general. She's travelled for a week out of the country and I texted her on IG teasing her not to miss me too much.

She replied by saying my "full name relax" with a laughter emoji. I then replied saying "a guy can hope"

She replied the following morning saying by laughing at my last text then wrote "Oh well... Good morning"

Any prices for guessing what this means and how I can escalate it when she comes back in a week?

Guys have you been on the end of similar exchanges? Girls, what does this mean?
