My relationship is quite complicated. I left my wife in late Feb 2020 after 7yrs of marriage, it was a very toxic and narcissistic relationship. Shortly after, I found and fell in love with my girlfriend. When we first started talking and chatting, she was very hesitant about being the “other” woman or the “rebound”. I constantly reassured her that she was neither of them, and that I wanted to have a full life with her (which was the honest truth). My girlfriend was very walled off due to being burnt in past relationships, and had been single for quite a while so she had developed a strong sense of what she would and would not tolerate. We eventually became official and shortly thereafter got engaged. Around June, things with the separation/divorce started to stall and it was starting to put me into a bit of a mental tailspin. My fiancee tried to warn me about the stress, but I was unable to comprehend it completely. I guess I started to become possessive, overbearing and controlling while I was struggling with my mental break. These were things that she absolutely refused to tolerate, and after I hit rock bottom, she suggested that I take 6mths to deal with my inner demons and discover who I am. Unfortunately I continuously messaged her every couple days, going around and around in circles for almost 2 weeks. I have been clinically diagnosed with ADHD and suffer from emotional dysregulation, which is now being controlled and managed. Unfortunately I have done a lot of badgering with my ex-fiancee, and really pushed her further away. She flat out told me that the traits she saw when I had my break, was not something she was interested in, and that I overstepped her boundaries and it was over. I tried to explain that I wasn’t able to see what I was doing, and I am sad/disappointed and hurt that I broke her boundaries, but I would never do it on purpose. I decided to try to push forward with giving her verbal space, while trying to do some sweet things for her (I used to make origami sculptures when we started to date) and leave them for her to see when she got to work (so she wouldn’t see me). However, that verbal space lasted a day. This morning I tried to be sweet and drop off breakfast at her place for her and her family, I didn’t even consider how creepy it was, but she told me it was unacceptable and super creepy. I apologized and went around in circles again. We eventually ended the conversation with her telling me that I need to see my therapist more because I am not handling my mental health well. I looked back to try to see what she was referring to, and it comes across as my constant circular conversations and badgering borders on harassing. I apologized to her for coming across as harassing, it was not my intent, I was just trying to grasp onto saving what I could of the relationship.
I am planning on doing at least 30 days of no contact, but I am wondering if 30 days would even be enough, or is any hope in this relationship lost due to the damage I caused?
