DP and I had been going through a really good patch intimacy wise. We faced a really big challenge about a month ago and I was so impressed with how he stepped up and it was great how we supported one another through it.
I'm keen to move on and take some positive steps forward in my life. I'm feeling things slip back slightly to a time when we were more distant. An issue I've always had but kind of accepted is that I have a few more interests than he does and he doesn't seem phased by this. I'm on a weight loss journey at the moment and am being really mindful about cooking us nutritious meals, doing home workouts, plenty of walking and some yoga. I'm also reading, journalling and creating moodboards, and find it really helps me. I try to discuss my challenges and goals and while he listens, he never seems to really engage or ask questions. It makes me feel kind of alone. From what I can see, DP only really uses any free time to scroll YouTube. I've tried to show genuine interest and ask questions about what he's watching and he does tell me about it but I guess I don't want to just ask all the time in case it comes across invasive.
All of this makes me feel that he lacks a lot of interest in both me and life in general. I'd like to address this with him but don't want to come from an accusatory standpoint. How is best to do this?
