I'm 26M , I met a very beautiful model 24F in the street, approached her and got her instagram, she was really cute and down to earth. After a couple months of superficial discussion (only about 4-5 story replies). I asked her out in January → she ghosted. In February she reached out again, saying she forgot to reply and she was very busy. First date, we went out 2 days ago for an activity : good vibe, but no physical escalation, only some touches on the shoulder, arm, and waist, she didn't seem to mind. The problem is when we were out, she was complaining all the time about her busy schedule in the next couple of months and when I gave a hint about our next meeting, she said she'll have to arrange to find time with her complicated schedule.

When arrived home I asked if she arrived safely and told her I liked the date, she replied that the it's mutual !

Question : Is she genuinely interested or just polite/friendly) ? Should I recontact her (if so; in how much time), let it go or wait for her (seems not realistic)?

I'm trying to play the long game here, since I know this girl gets hundreds of demands so I'm cautious with my approach
