Having girlfriend/ex girlfriend problems?

Hi, so recently, this girl I had a crush on asked me out, I said yes and we planned a date for the week after. But then two days later, she broke up with me, saying she still has feelings for her ex. She said how excited she was for the date thing and if we were still going, I felt bad saying no, so we kept the plans. Two days after, she texts me and asks me if I told her ex that we were flirting, I said no, I honestly have no clue who your ex is, she told me how her and her ex were having a pretty heated argument, I tell her I’m sorry that’s happening, yada yada yada. So we started talking a bit more like we used to, and every so often she throws in some heart emojis, just like she used to when we were dating. So its the day of the date, I’m about to go and she has to cancel because of family issues, I get it, no big deal. So I tell her it’s fine, she keeps saying sorry, and asks if we can plan for next week. I say “yeah, sure” and that’s that. But now I’m really confused, because I feel like she likes me, but I’m not sure, and I think I like her but I’m not sure.
