need breakup advice
So im not really good at explaining things but me and my ex have been broken up about a month and a half so far, she left me because she needed space and time alone, at first she said she wanted to take a break and stop texting but still to text goodmorning and goodnight for awhile then rethink our relationship after the time, i messed that up by bringing up how i didnt feel like a piority in her life during the relationship and she ended up changing her mind and to fully breakup with me, we broke up on a monday and it was kind of a mutual breakup, but the next day i ended up bringing up how we could fix things and everything could be better but she declined and said she is making the best decision for the "both of us" then said its best to go no contact until we talk about exhanging our things. during the breakup she said i was a good bf and she really liked our relationship but i guess she had to much going on in life? about a month later and like two different texts about meeting which didnt work out which were nice and not mean in any sort, we finally met up and she acted very cold. I tried my best but i definitely showed emotion and awkwardness. when we first broke up she asked to keep our promise ring because she "doesnt hate me and wants to remember our relationship by having it" but when we met up a month later she said nothing about it and had it in the stuff we exhanged, after the meetup i was pretty emotional and ended up texting her when i got home a bunch of things, nothing angry or sad but just memories and how if we really tried we would work, she said the meetup was hard for her too which is why she rushed it. to the long text i sent she said she didnt know how to respond and that she was sorry, then she said we should go back to no contact but said she will think about everything i said, ive been doing "better" but shes definitely on my mind alot more then not and her birthdays coming up. is there a chance she comes back and should i wait? i know i have to move on and work on myself which i have been doing but its hard to keep her off my mind anymore. especially after the meetup it has been hard. She also told me shes not leaving me for anyone else and she doesnt want anyone else but she said she wasnt sure she would come back to me or our relationship but "wouldnt mind a text in a few months" what do i do?
