So 2 days ago a matched with this girl on bumble, after one hour she messaged me and we started talking, we exchanged only few texts cause we both had to go to sleep. Yesterday we text again, we talk a bit but she gives closed answers and almost never ask questions back. After a while she asks for my IG and i give it to her, she follows and i follow back, so then I asked her if she wanted to hang out with my friend and I (we were going to a concert close to where she lives so I decided to try and ask her out) and to bring one of her friend with her. She answered that she had planned something with one of her friend (1/2 hours before that I asked her if she already had plans for the night and she said no). So i just text her " alright, no problem, have fun Tonight" and she says "thank you :)" not even a "you too". I don't get if she is interested or not, what do you say?
