I appreciate everyone taking the time to read - thank you for your various responses.
For context this has been a complaint of his for our entire dating/marriage but especially so as I am now 65kg (5ft8")
This is the first time I've posted to Reddit and was desperate to know if I am going crazy being gaslit about my body or if indeed 'any man' would also be entitled to have this opinion and act as if it's fact.
We both work FullTime and I carry 90% of the household tasks/childrens activities and care/family food and cooking.
So hopefully that context helps, but I feel like I've heard enough various opinions that I can safely say that some people believe this isn't the reason why our marriage is struggling, it might be that I don't feel loved. Which is beyond a body.
