sad despite things going kinda well

So I met a girl, we are both 19 and we went on two dates and at the second one she asked me out again Tuesday but unfortunately she had something else to do with her family and now idk what to do because I get a vibe of her losing interest…the next date is not planned yet (she said we will find a day, I promise).. we are texting every night with gn messages and flirting a lot, she is clearly a bit into me. However I feel so depressed because of my past experiences where everything worked fine until a girl gosted me out of nowhere… Day by Day o feel more attached to this girl.. We never kissed yet but we hold hands a lil bit .. What should I do? Am I losing her? What's wrong? Maybe she senses that I am getting attached by her and pulls back… 🙁 I feel like I can't lose a minute with this girl cuz I will lose her but at the same time I feel I'm rushing
