I’m sure that the vast majority of posters who still have their OH value them and are grateful to still have them around, and will be devastated when they lose them; and will also feel for those who have already lost their dear partner.
However, it is human nature for every single one of us to have our foibles which may, at times, irritate our OH. Posters coming here to express an irritation and seek advice about resolving it is fair enough and they shouldn’t be berated for doing so or be made to feel in some way ungrateful because they have these niggles and seek advice.
I think, Lottidot that you and your DH are probably still negotiating his recent retirement (8 months isn’t very long). It’s an adjustment for both of you. ( My DH has been retired almost 2 years, and I’d say we are still adjusting to a degree).
You don’t actually say, but if you’ve been at home on your own for some time before his retirement, then just getting used to him being around all the time takes a while to get used to for both of you.
Is there another room you can take yourself off to occasionally?
Has your DH got any outside interests that you can encourage him to become more involved with (or for that matter, have you)?
This, perhaps would help you not to notice his chatter so much when you are together, because you’ll both have things to chat about, and you’ll both have had a few hours to yourselves, following your own interests.
