Starting a 90 day hard mode challenge that could be permanent

Hey. I've started this 90 day hard mode challenge. My wife told me this is my last chance. But follow up conversations reveal that she doesn't love me anymore and I've destroyed the marriage with this addiction and self hated. I get that it's over and we need to heal. I'm going though a lot right now, so try not to be too hard on me, but my biggest fear is that I'm never going to have sex again. A huge part of the addiction is that I've treated my wife as an object of my desire and not taken care of her emotional needs. So, were getting a divorce. I just really love having sex with her. We had sex a lot because it was supposed to help us stay connected but it wasn't enough to overcome the hurt from not connecting with her emotionally in other ways.

How can I come to terms with this idea of never having sex again? This is really tearing me up inside.
