This girl ignores me then hits me back up only to ignore me again. Should I ask her what’s going on or forget it?

So my sisters friend and I have had some sexual tension between each other for 3 years now. I asked her out a few years and she kept cancelling. I stopped talking to her until hung out with her and her friends one night with my friends. She came up to me and started flirting that night. Her friends told me that she likes me but my sister doesn’t want her to date me. Anyway we started talking a little bit and then she ghosted me again. Then after two months, she texted me this Friday night asking to talk. She then explained that she’s sorry for how she behaved and that she’s really into me. She went in to explain that she doesn’t care about my sister figuring out and that she wants to go out. I told her that we should talk the next day. When I texted her that she didn’t respond/reply. I texted her the next day and she hasn’t replied anymore. I want to know if I should text her again and ask her what’s going on, cause I’m genuinely confused and it’s depressing me? We’ve never had sex or even kissed, cause my sister was always present.
