I need some serious help

How do you move past something YOU did to your spouse to hurt your relationship? I’m having a really hard time forgiving myself. My husband is willing to work things out. It’s been 4 months since it happened (I sent a pic..nothing physically happened, nothing emotional...but still not ok at all) and I can’t seem to not keep blaming myself for how our relationship is. I feel like I project my insecurities on him so much and he wasn’t the one who did anything wrong.. we have gone to therapy together and I am starting to go on my own now but I just don’t know what to do to help with the guilt and to see a light at the end of this for our marriage to be stronger or better. I don’t feel like he looks at me the same anymore, which I completely understand. But he loves me and is willing to work through this. But I can’t seem to love myself and that was the problem from the very beginning of it all. Help 😭 please no bashing I already feel horrible.
