I'm not sure what to do

I'm a 20 year old male and was dating a 20 year old female. Both of us is our first relationship, With the attachment theory I'm not sure if she's a dissmissive avoidant or a fearful avoidant since she exhibts both of them. We were friends for a year and we had great chemistry. We dated for 18 months and we broke up about 4 weeks ago. There were some issues in our relationshipwith her not expressing her needs but we were able to work it out most of the time. Besides that the relationship we had is really great, we always dm each other every single day and go on dates every week before COVID hits. I'd admit that I made a major mistake going passive aggressive and being petty in the last few weeks of our relationship. After the weeks she wanted a break up and I asked her for a two week break which she agreed. During the first week I only sent her one message apologizing what I did and how I was going to fix it. Then after that she said her feelings were the same that she doesn't love me anymore and she said suggested we can be friends. But only after 2-3 months after no contact. She also said that she understands if I never contact her again. I didn't understand it at first because two days before she stated about wanting to break up we got into a long phone call where we played a new game together.

Now it's been almost four weeks of no contact and I feel that I have recovered from the break up feeling way better than the first week. But I still have feelings for her and want to work things out with her. I would also say that she still looks at my story on snapchat and still sharing her location to me. She also have been going away from social media a lot since the last four weeks. I'm not sure what to do now since like I saw a bunch of youtube video saying doing 30 days no contact. Would it best be to just reintiate contact casually then slowly come back to the topic?
