Sry if this is long but I had to talk to someone

Backstory: My gf and I have been dating for two years at this point, we both met in the same university and we had some of the best moments of our relationship together, but after the end of freshman year she ended up transferring to a different university and we decided to continue with long distance! We He had made plans to visit and keep in touch and everything seemed to go well for the first couple of months during which we did visit nd talk every night but then Covid hit and we weren’t able to visit each other anymore. During this time because of her schoolwork and our communication being only through text and video calls. somewhere it started to feel like the relationship was going off as our talks would get repetitive, or she wouldn’t wanna watch things at night/day with me nd chill out. there would be times where she wouldn’t text me for 7 to 8 hours back cuz she would be busy or working. We weren’t even celebrate our 2 year anniversary date cuz she had work so we postponed it but it still didn’t happen and just kept pushing it.
We communicated, wherein she mentioned that during the day she didn’t think about me or have time to do so; but still loves me a lot.. but we came up with a few ideas nd decided to work on our problems and move forward with it, and it was beautiful for a while but then those issues started rising again and we decided to take a break which lasted no more than 12 hours! After this We thought we knew we wanted to be together. Our relationship was going to well we gave each other our space but talked and called most nights and had good moments. I am unsure of what happened, as last night we had a fun call, today however, my girlfriend didn’t text me at all and at night during our FT she said, “ she feels we need to re-evaluate our relationship. She feels after transferring to the different unit she became a lot more independent as she relied upon me when we were together and now feels we don’t think on the same wavelength anymore and don’t connect the same! And feel we should take a break and see where we stand” . I love her so fucking much, she was my baby and I saw her as my wife so this just crushed me and I was utterly destroyed. She also mentioned that she doesn’t think about me during the day or have any inclination to make contact but still loves me. She feels like there should be a natural inclination towards her to do that but she doesn’t feel it. Whilst i believe this is important, cuz i still have that inclination towards her! I feel the reason this is because we don’t spend enough time doing activities together it’s either just the ‘wyd’ texts or the gn calls!

Break: We have decided to take a 1 month break, she originally wanted to take two, and have decided to FaceTime sometime next month. However the break and the conversation happened so quickly I have no idea what is the point of this break? I believe problems could be solved together and in this situation, certainly spending more time or FaceTimeing each other more could’ve possibly helped!?? IDT I can remain no contact with her for a month!! It’s only been the second day and I am numb and she is the only thing on my mind.

This sucks soo hard, can’t figure out where did I go wrong or did I fail to do to?? What can I do to help calm down and what do I do from here?? How should I take this break, I am afraid to go no contact feeling that she’ll completely forget me, is it over?? :(! Should I text her asking what she looking out of the break and that I am missin her and make some mutual guidelines or give her time like a week before texting her .
