Break up that feels wrong

Hello everyone,
A few days ago my girlfriend of 2 years and 7 months broke up with me (i am 22 and she is almost 21). She said she didn’t feel it anymore and she missed me less than normal. Everything was perfect for 2 years and 5 months. There was much love and intimacy coming from both sides, we were both so happy with eachother and we never had big beef, small discussions of 15 minutes yes but no beef. But then it changed. We didnt see eachother for a long time (we had online contact) because of finals and separate vacations with our families and when both back she also got COVID. During those 2 COVID weeks it started changing. She told me she felt she was making evolution as a person the past 2 months, which is normal at 20 years old. She told me she was searching for herself a bit, searching what she wants. She now has the urge to spend more times with friends (which she didn’t do when we were together, although i tried to make her see her friends more) and she also wants times just on her own. She says she can feel happy when she is alone for this moment. I am still in love with her, for me she feels like the one. She told me that she does not want that i keep hope to get back together because she does not want to keep hurting me and she still likes me as a person and doesnt wan to lose me so she would like to stay friends. I know she loves me as a person, she told me explicitly. (maybe even more idk that but right now it is just repressed because of the situation and she wants to do everything correctly to not lose me entirely)

We both study at college and are in the same years and classes, so we see eachother almost daily. At this moment we don’t contact though. Should i keep no contact? Or should i act normal with her? We did talk yesterday just because i did not understand the reasons at first. What should i do now? Keep the contact? Or do a no contact for a while? Also now (6 days after the breakup) she sent me some pics of her dog, whom really liked me and i liked him too. I responded short. What do i do if she stays sending me stuff, do i tell her i am not ready to chat casual and i need some time to process all this so we could become friends? Do i tell her already now or do i wait till she sends something again?

I am in two minds right now. On the one hand i just want to be back together, because we had such great times, we were so much in love and we always felt happy with eachother. But on the other hand i don’t want to lose her completely and if we really can’t get back together, i want to be friends with her because we were quite literally also eachothers best friends. She also does not want to lose me completely. We both aren’t interested in someone else or something new, she explicitly told me that. I don’t really know how i should handle this whole situation. What do you think?
