I would take out the word expectations. Having hope is maybe softer and truer.
Physical intimacy and emotional safety go hand in hand. It sounds like you understand that your past coercive ways in your sexual relationship did a lot of damage, and then adding the cheating and the porn, so sex has become weaponized over time. It was the avenue of abuse, and so one can understand why she isn’t willing to think about risking going back to tha type of torment.
Saying you have expectations even if they are vaguely off into the future is probably a statement that is counterproductive of what your goals already are.
Is it reasonable to think you both will abstain for the rest of your lives? No, I think that’s a highly unreasonable expectation. But right now her head isn’t moving in the direction of opening up intimacy and this conversation creates pressure which is reminiscent of your coercive demands about sex earlier in the marriage. Threat might be a strong word but considering the history here that pressure very well can feel like a threat to her. Instead it’s better to let her know that you love her, you understand and are sorry for the damage and continue working on yourself. That you are hopeful of building a fully mutually beneficial relationship and will take her happiness and wellbeing as crucial a your own.
Instead of worrying about the future, focus on the present and how you can build emotional safety and bring more emotional intimacy into the relationship. It sounds like you are taking steps in correcting the behaviors but it’s going to take her a long time to trust you and open her softness towards you again.
It may not happen. That’s the risk we all take when we try for reconciliation. What I think made my personal quest successful was learning to focus on my side of the street, becoming the type of partner I wanted to be and knew I was capable of, and doing my best to show him consistency, love and patience no matter where he was in his ow healing and no matter what he was or wasn’t willing to give in return.
You both have to do the work of healing. So of course it would be your hope to have a full on marital relationship again. That’s natural and true. But it’s equally natural she is not even ready to start thinking about what that looks like as her pain and uncertainty is all encompassing. Focus on that. Keep finding more ways to build trust, continuing to show patience and love towards her while you stay committed to working on yourself will be the only way you can prove you really do get it and the two of you aren’t going back to that hellish place.
So in essence I think you are right that staying married would eventually mean navigating intimacy. But putting the word expectation to it, would reasonably sound like a threat to someone who can’t imagine you having a loving sexual relationship while healing from one that created so much damage because it in essence taught her that was what you value most over her needs, wants, safety. It made her feel like that was her value to you—and that’s so devastating because anyone could fill that value it made her feel there was nothing special about her. She felt reduced to being a convenient way you could be serviced.
Think about ways you can show her differently, without love bombing her and creating more pressure. Start with small stuff - give her specific things you love about her. Not all at once of course but quietly over a long period of time. When appropriate also make very specific apologies in the context of situations you encounter together. Take things off her plate as much as possible- chores, errands, parenting duties. Give her time and space whioe consistently showing up and proving she matters.
There are no guarantees you will successfully reconcile. Therefore there are no guarantees your sex life will be rebuilt again. Focus on not getting the cart before the horse.
I can hear you are making progress-just keep doing that. If you do it will give you the best chance of reconciling, and if you truly reconcile she will be willing then to work on the intimacy. Right now that’s too much for her to think about when she is just trying to get through today.
