I'm (20m) having trouble identifying what me and my friend's (19f) relationship is and I don't know how to confront her about it
So me and her have been texting almost every night for a couple months now and we only stop texting once one of us says we're tired and have to go to bed for the night. The conversation have ranged from super casual "how do you feel about this food" "how was your day" to much deeper and more serious personal topics. And there's been a couple times where I feel like she's said a couple things that could have referenced us being together as a couple. We see each other every week but it's not really a time to hang out (we have work to do) and she lives almost an hour from me so we don't get to hang out in person much but when we do it's usually with one of our other friends.
However, there was one time a few months ago when we went to an amusement park and our other friend couldn't go so she asked if it was ok if just me and her went and I said yes. We talked A LOT that day and later in the day there were a couple times where she laid her head on my shoulder (I got super scared and froze every time she did it AHHH). When we got home that night she texted me saying how much fun she had and we should go more often. The problem is that this was the time in the year when we were both crazy busy and literally could not hang out at all (we still kept texting every night though!).
So fast forward until last week we went to a music festival together (we had planned to go to this festival together about the time she started texting me every night), this festival was the first time we had really hung out since the amusement park because of our schedules. Again, there were a couple times throughout the day where she laid her head on my shoulder but the big thing for me was at one point we had to run from one stage to the other to catch the band we wanted to see and she grabbed my hand and we both started running. This was halfway through the day and she had never before this done anything to make sure she didn't lose me in the crowd. And I had so many other things on me that she could've grabbed to not lose me but she chose to grab my hand. Whenever we were walking anywhere the rest of the day we were holding hands and for one of the bands we saw we stood and held hands for the entire show. And I even had the courage to not freeze up one of the times she laid her head on my shoulder and I laid my head on her head and we just sat there for a while it was really nice.
But even after all this we've never explicitly said we're dating and I don't know how to confront her about it. She's the most caring person I've ever met and the last thing I want to do is lose my friendship with her but it's not healthy for me to keep beating myself back and forth on whether we're dating. I don't know if it's more appropriate to ask her on a date or ask her for clarity on if we're already dating?
tl;dr my close friend has been texting me every night and there's been times when we've gotten close and held hands but I don't know how to confront her on of we're dating or not
