This seems to have become a thread about my weight. For reassurance of those concerned I'm well aware of the risks associated with obesity and - like many people, male and female - have struggled most of my life to manage my weight better. It goes down and it goes up. I do my best to minimise the impact and risk to my long term health.
@Diycheater your assertion that I suggest things she can do (counselling, change her meds. etc) whilst absolving myself of agency or responsibility is a little ungenerous.
I came here to seek advice on how I might address an issue that is affecting our relationship constructively and kindly. I've had lots of helpful input on how counselling - me alone, or us together - might help. And on how to raise or suggest it.
Meds. has come up in conversation over the years - most recently when she discussed HRT with her GP following her hysterectomy. Her menopause symptoms were not so bad at that point and - other than a potential increase in libido - her conclusion was that there were no benefits that outweighed her wish not to try it. She wants to minimise the overall amount of medication she takes, and I respect that. When that changed (symptoms worse, and one other med. stopped) she started HRT (and as it happens it made no difference to her libido, so her initial call was a good one).
In any loving and intimate relationship there's always the possibility of health issues that result in caring. Or in an unequal distribution of chores and parenting. I could fall ill or be injured in any number of ways (not just because of my weight). For me that's 'for better or worse'.
If I was to fall ill and need to be cared-for I like to think her response would be something along the lines of "that's fair enough - he has cared for me through my mental and physical health crises over the years - he has supported me emotionally, mentally, physically and even financially (during those years I was too ill to work) - and he has been an active and present parent when I have not been able to."
I might be wrong. And frankly if we still had kids at home I hope very much I would be brave enough and well enough to leave so she could give what time and energy she could muster to looking after them. (She's quite explicit about the fact that I could parent without her far better than she could without me.)
I'm 100% confident that her response would not be "no sorry - he needed to try harder to lose weight over the years - giving up alcohol, swapping his car for a bike, doing at least twice the recommended amount of moderate exercise per week, eating low-carb, intermittent fasting, etc. all that just wasn't quite enough effort."
Anyway - apologies for the length of this one - clearly touched a nerve. I'll be ignoring further posts about my weight (they have made the thread a little toxic for me) but further perspectives on how I might work with my partner to restore sex and intimacy continue to be welcome.
