I met up with my "partner again" and revealed all the disrespectful stuff I've done in the relationship (not full-on cheating). For context, he downloaded a dating app 3 months into us dating, I found it without him telling me, I forgave him. Ever since then whenever we argue or he wants space from me I always assume he's cheating or speaking to other people. I've been cheated on in every relationship I've been in, which he is fully aware of, so finding that app on his phone without him being honest with me obliterated my trust in him.
I tried to justify that me doing the same thing behind his back was okay (this only happened when he didn't want to see/speak to me) but it just made me feel guilty. I took it waaaay too far when he suggested a break two months ago and let the disrespect get physical (I told him about this *first post). He forgave me and allowed us to restart the break. I've realized how much I truly care for and want to be with him. I saw him for the first time this Friday after 2 weeks of no contact. I promised him and myself that I would follow 100% the rules of exclusivity and while I felt incredibly lonely I did it. But seeing him made me want to share even more (less severe) disrespectful things I've had since finding the dating app. Now that I've said all the bigger details of what I've done there's nothign really more to share. My anxiety is so strong I feel like if I don't give every detail of disrespect instead of just overarching things, I'm still lying to him. I told him this and he reassured me that I can share them with him if I want, but it's not really necessary as it would just make him more upset. I know it's very selfish of me to want to share every single little detail day by day and other people I talked to try to help me by saying "If you didn't do any of his non-negotiables try and let it go". I did not do anything he considers a non-negotiable, but the guilt is still eating me away. It's like going through airport security knowing you don't have a bomb in your bag, but feeling like they are going to find a bomb. I've been racking my brain going over and over anything I've done to tell him more wrong. I can't think of any other than the tiny details but it's been making my chest hurt.
I was very happy seeing him this weekend, but I just feel guilty now for all I've done. He reassures me that he wants to start again and hopes that we can become better partners for each other. I told him about possibly having BPD and he was very understanding. I'm really considering mood stabilizers so I won't have such strong reactions to separation, anger, or disappointment. I don't feel like I deserve him (I told him this). The only person I know who would accept this level of disrespect and worse is myself. I don't understand why he wants to be with me even after he tells me. How do I stop feeling guilty? Do I tell him every single little detail? I don't know how to forgive myself but I promise this will not happen again. How do I stop feeling like this? Help pls...
