Question about proper response and tips

just got back on tinder and matched with this girl who is sort of the rave/party/hippie type😂 the past 3 times I’ve had tinder ive matched with her. The first time we talked a good bit and I asked for her number and she gave it to me (I never saved it cause she never answered). The second she just texted me saying she remembered me and it didn’t go anywhere. Now she just texted me saying “U again.” First off how should I reply to this and second what do you guys recommend I do to try and hang out with her this time? (To summarize just asking how to sort of restart the interaction and try to hang out with a girl that was being difficult to hang with last time)
