I don't normally reference other threads when replying, but given you've mentioned it here I've just read your posts on that other thread - just yours, none of the responses.
You talk about how you nearly left him a few years ago and after he begged you not to you had a period of a few years which were good but you let them slip away because you were "too depressed about not being allowed to leave as I thought there was a better life out there that I could not see the wood for the forest.".
You also say in the OP in that thread that you have had one foot out of the door and been emotionally distant for years.
You call him narcissistic and emotionally abusive for being "grumpy and disgruntled and unhappy" and not quite contributing 50:50 to household decisions, but you have not given any concrete examples of anything that is actually abusive or narcissistic behaviour.
People telling you to LTB on that thread were taking you at your word that he behaved that way, even without specifics that evidence it, because this is Mumsnet where there is a tendency to whole heartedly support a woman who says that she is being abused - especially on the relationships board. In most cases this is not a bad thing at all - however, in your case, I think it has done you a disservice, especially in light of this thread.
On this thread where you have accused him of having a fetish and got angry at him simply for suggesting sex at a time you deem inappropriate and you have been almost unanimously told that your reaction is hyperbolic to the situation.
Taking these two threads together, I suspect this is not the first time you have reacted in an OTT way to something he has done that is fairly innocuous and given, by your own admission you have been emotionally checked out of the relationship for years is it any wonder that your husband is grumpy, disgruntled and unhappy?
I would like to hear his side of the story of all of this, because based on your posts and your own words alone - there is someone in the relationship that is emotionally abusive, and it isn't your husband!
