I want to break no contact so bad..

Hey everyone I really could use some advice. For context my ex girlfriend broke up with me exactly a month ago and it’s been extremely hard and I miss her so much. She called me that day to end things saying that I wasn’t “prioritizing” her and she also assumed that I was talking to other girls when I clearly wasn’t. I feel like she had trust issues and trauma, since she told me her past relationships were abusive and they ended up cheated on her. We only dated a couple months and it was the absolute best time I ever had, the last relationship I was in was way back in 2018 so yeah this breakup is hurting me so much.. but i really want to send her a final message that I have saved on my phone, just pretty much thanking her for all the memories and saying goodbye. Another reason I want to send it is because we’re still friends on social media and I see her posting, sharing and reposting stuff throughout instagram and facebook about breaking “no contact”. I saw one post for example that she liked and it said “no contact but I still think about you”. It gives me hope but another thing that’s weird is when we were together she also told me she would always block her ex boyfriends on social media but it’s weird considering that she still has me even a month after we broke up. So is that also a sign that she possibly misses and is waiting on me to contact her?
