Morning all!
Hope you are all well.
I have been pondering your post @capamapadapa and wish I had an answer for you. DH and I have been a couple since late teens and were friends before we got together. We are never short of conversation and DH regarded his job as something boring he did to fund his hobbies!
I have such a restricted life nowadays but I have always encouraged his hobbies so at least one of us has some fun. I like to have small projects and I research things to do with them. Local/family history, sewing, mending. I save them up for when DH is out and bore him about them when he comes home 😉Likewise he does research on the history of his main interest and gives me a blow by blow account of his findings so we are well matched in the boring department.
I think we would manage without talking about children/grandchildren, there's a lot of other stuff. You must have other things you both enjoy? Something like planning a project, big or small? I am looking into hydroponic gardening at the moment. I probably won't actually do it but I have enjoyed learning about it.
There's a million things you can do for your own enjoyment, you don't have to entertain your DH. Occasionally I get very down and feel like a burden but that passes when I'm less fatigued.
Sorry for my ramblings. Just a few ideas!
