Girl ghosted me for a month, came back apologizing and pushing to hang out, but is still actively on Tinder. why bother?

We went on two dates, things seemed to be going well, then she went quiet for over a month. Out of nowhere she texted apologizing, said it was just school, and asked to hang out. I said I was busy and left it at that.

Saw her at work and she apologized again in person and asked if we could ever hang out again. I said sure but never followed up. Next time I saw her she brought up that I never texted her to make plans. I told her honestly that I didn't trust her anymore because of the ghosting. She said that was fair, swore it was just school, and I said we could hang out this Friday because she's been persistent about it but I still don't really trust her.

Problem is she seems to be very active on Tinder. Why is she so adamant about reconnecting if she's still out there looking for other people? Is she trying to keep me around for attention? Considering canceling Friday but not sure if I'm being rash.

And why is she expecting me to still reach out to her and do all of the planning still?

Please read: I'm currently very conflicted because I asked this question on askmenadvice and everyone of them told me I'm just a backup, whoever she was with for that month didn't work out and Im just someone she's using while she shops around. I'm wondering if it's any different from a women's perspective.
