I did no contact but messed up

Alright ill tell my whole story:

me and this girl dated for just under three years, about 7 weeks ago she broke up with me. i felt it was really sudden so i sort of flipped out and begged and pleaded for almost two weeks! can you believe that?

anyways 2 days after she broke up with me she was with a guy who she had known for awhile but i always felt like she was too buddy buddy with, so id tell her to stop hanging out with him many times, she never did and said to just trust her, so i did.

about three weeks after the breakup i began thinking of ways to get stuff done by not begging and decided to do no contact. (WHICH IS AMAZING) once you get over the point of feeling the need to talk to her every second it is a lot easier. i began improving my self physically and mentally, im more understanding and calmer and i look back and see that maybe the break up wasn’t so sudden, i was just not accepting that i was as bad i was being.

so a few days before no contact was over i had to go to the hospital, not fun, so she noticed i wasn’t coming in to school so she sent me a text asking if i was okay. the next day i explained i was in the hospital and she began being friendly towards me. so we began long texting conversations and thats where i began messing up. we talked too much, and i didn’t realize, the breakup and past relationship came up and that was a mistake to talk about. so i came into school about 2 days after our texting and she was actually happy to see me and explained she cared about me and blah blah blah. i felt i was really good in person and she even pointed out my new personality and looks. i even caught her staring at me a few times.

But since ive began talking about our relationship with her she has said that she doesnt forgive me for how i was and was upset i didnt help her with her anxiety attacks (which she had a lot, and i always tried to help as best as i could, it makes me sad she thinks i didnt even try) anyways i accidentally guilted her by speaking my mind and saying i wished she wouldve actually let me realize how wrong i was acting then let me try again. so now i feel bad because
1.) i guilted her, leading to an anxiety attack for her which i tried to help her through
2.) i realize i messed up by talking about the past relationship and breakup

anyways im starting another no contact to try to restart and improve myself more to stop the negativity, should i do this or keep talking to her, but at a more limited pace and be more positive and polite, or something else?

I really feel like ive made progress, so i want to continue. thanks for any help you can give and thanks for reading it all!

Thats the 5 steps for. No contacts mean no contac at all, break it down. Make time for yoy both, do your things and let she do her things… Take the steps slowly and patiently, it helps, really! After the time you feel ready to re-contact(post text or email, step 4) be more confident and yourself, try not to metion relationship, otherwise she will build a wall around herself again.
