Based off your post you come off needy and most woman can sense that.
1. No contact. Don’t text, call or nothing. Women strive off attention, if she likes you and you don’t contact her I guarantee she will try and contact you at some point.
2. Don’t ever get into conversations through text. Texting is to setup the next date or plan period. Getting into emotional conversations through text is quickest way to get friend zoned.
Next time after your date, give it a few days maybe a week and just shoot her text “ I’m going to this festival next week and got an extra ticket, you should come! And just leave it at that and see if she responds. If the likes you, she will get in contact and give you a definitive yes or no. If she doesn’t like you she’ll most likely keep ignoring you and you move on to the next.
