Hi Jack,
Thanks for the nice compliment! I have to find something to replace the thing I want to change, something I value just as much, or I just have an awful time. So I still do eat sugar occasionally, it's just a zero calorie natural sugar. And I love chocolate, so I do a smoothie or a home made nutella with cacao which has no sugar, ... But before I discovered those things, I ate pistachios that I measured out before hand, because they are an appetite suppressant, and I love them. And I discovered that I really do value my health more than the sugar, so even if I don't substitute ohter foods for sugar, I think about what staying addicted to sugar does healthwise, and how once I am off it a while, it doesn't even taste good anymore.
I think it is the same with my relationships. I wanted people around me to change, but what I really wanted was a feeling of peace and well being, and the only person who can give me that is me really. So I worked on just giving myself what I needed more of. My husband is more like you and your wife where when he relaxes it is doing hobbies outside of the house usually without me, and I am a one on one person who loves hanging out and talking and sharing experiences (which we did a lot more of in the past, but I can no longer get him to do much). So I am doing things for myself instead of waiting for him to do them with me, and although I didn't think this would work for me, it actually does. So I found good substitutes!
My husband doesn't do well with sitting meditation either, but loves running and getting into a meditative state. I have been taking long walks and meditating while doing them, and that makes me so peaceful and happy. Just don't worry if you are doing it right. There are so many ways to meditate and reasons to do it. Just learning to be more mindful of your surroundings or to learn to relax and feel your breath in your body or to feel all the sensations in your body or to drop your attention into your heart area and get out of the head are all so beneficial. Just remember to do things in a relaxed, experimental way and see what happens. And if you have thoughts, that's fine, just keep bringing your attention back to what you are trying and let the thoughts do what they will - they are going to wander like little clouds going across the sky, so just let them do their thing and don't give them your attention. And you don't have to meditate a long time to get the benefits. Meditating twice a day for 5 minutes is way more beneficial than trying for 20 minutes and giving up! If you try it, let me know how it goes!
