I think my friend likes me but I don’t know, but I also have a small crush on her. I (19m) can’t tell if my friend (21f) likes me and is flirting with me or if I am just being dumb

So this has all happened within the past few weeks. A girl Im friends with at college is a senior, and I will be a sophomore. I jokingly said that she should help me practice kissing for next semester and she said that if I didn’t kiss at all when I graduated she would kiss me. I then jokingly said that I gotta wait three years and then she said that she’ll do it at her graduation instead which is next year. She is 100% serious. What does this mean? Does she like me? Think Im attractive? Or just wants to do something nice for me because she’s a really good friend? I sorta like her and find her pretty attractive but I already like another girl who just got in a relationship. She has told me she likes another guy but she hasn’t really elaborated much past that. However she knows the guy she likes doesn’t like her back. She wanted to FT me that same night to fall asleep because she’s wasn’t feeling well and having birthday depression because she doesn’t like her birthday. What does this add to the story already talked about?

Then cut to the day after where she went swimming and when she told me I jokingly said to not send swimsuit photos and she then later sent a mirror photo of her smiling, however she was in a tank top and jean shorts and not her swimsuit. Then a couple hours later she sent me another mirror photo in said tank top and jean shorts showing me her sunburn, she was making a sorta laughing smirking face with puffed out cheeks. However she sent a photo to a group chat we are both in but it was a different photo of her. It was definitely taken back to back with each other and the gc photo was more a goofy face/expression. Could that mean anything?

Then fast forward to that night where she asked me if she could send me a photo of her “looking good” (her words). I ofc say yes and she sends another mirror photo in a black tank top and black nike pro shorts, while having a flirty smirk on her face. She said she needed approval before she sent the photo to her mom and when I asked why she need approval to send a picture to her own mother, she responded with she’s scared of sending photos to her mom which I asked why and she replied with “Idk why I’m weird ok.” She then told me that she used to have someone to approve her photos but doesn’t anymore and that she can be herself around me, I told her she can always come to me for approval and she said she appreciated it. Was that photo meant for me or actually for her mom? Is she genuinely just wanting my opinion on photos of her? Or is there something else Im not seeing? Then another day she was out boating and swimming again and she sent me a picture captioned “I hope I stay this tan” and its just a photo of her sitting down and her camera is just showing off her thighs and legs. Is there anything in that or am I just being crazy?

Cut to tonight where we were talking and I sent a goofy photo of myself that was a really bad photo of me and she hearted it. Then she sent me photos of where she was on vacation too. I said that I am moving there tomorrow jokingly because of how beautiful it looks and she said “lets share an apartment” to which I responded with “Dw I’ll get a single bedroom one” to which she said “Smash.” Then she said she was going to bed to which I said “without me cmon” (thats how we joke, we aren’t cringe or weird trust me) and she said “No you’re supposed to join stupid” and then I jokingly said again “I’ll come as fast as I can, Then we can go to sleep.” (Again possibly cringey but its our humor) and she said “Sounds good” and then I said “I’ll be big spoon so you aint cold” and she responded with “Bet” and then we said goodnight and I love you to each other (we say love you all the time). What does all of this mean?
