My sitch is different to yours (feel free to read up if you want), but one of the reasons that my H left me was the fact that he said I never opened up enough. I’ve made the change and shocked my H, he’s aware of the change, he’s not said anything directly to me yet. It was difficult at first, but I’ve done it and it feels good. Took me a while to get used to feeling vulnerable and letting my guard down.
Work on this, it will be of benefit to you and any future R you have whether it be with your H, family or friends.
