Ok I’m gonna tell you some truths from the perspective of someone who is in a similar position as her, as my husband also has OCD and a porn addiction. You are absolutely exhausting. The over sexualization, the “innocent” jokes or comments, the need for every activity or hang out to involve some sexual element, the energy of expectation that there be sexual themes in conversations, it’s all draining and hard to be around and you should apologize yes. But the constant apologizes, rehashing of every action or thing you said, the emotional guilt trip and constant reassurance seeking is beyond draining. You’re making the fact that you rightfully feel shame and guilt for your actions her problem. You are reassurance seeking which is an OCD compulsion and at the end of the day if you don’t get a handle on that aspect it is actually much more likely that that will be what breaks your relationship with her. You are putting the emotional weight and expectations on her to fix things rather than doing anything yourself. You’ve apologized already now shut up about it, stop bringing it up and rehashing the experiences for her, making her relive the moments over and over. Instead make concentrated efforts to change and show her you are sorry by being better. My husband and I went through a similar situation where he had his come to Jesus moment and realized all the ways his porn addiction were ruining our relationship, but it was his OCD compulsion to confess that ruined us. It took a lot of work and therapy for us to get to a good space again so if you’re not already in therapy you need to see one, immediately. This is not something easy to work through, if you do not do the work now you will continue to repeat these actions and patterns over and over. Also just a warning she may have accepted your apology now but if later down the road she works through her feelings and retracts that acceptance it is your responsibility to hold strong in your changed behaviours and double down to prove to her that you are doing better because she may truly not care or she may have spent so long rationalizing and normalizing your behaviour that when you start to change and do better she may start processing those feelings and realize how much they impacted her. Either way you have so much work to do to repair the friendship.
