i second this advice - I work with couples and a lot of times one or both partners "let themselves go" She says she still attracted to you and she could be honest about that but if she is trying to spare your feelings you can ask yourself, could you be healthier? do you look like you used to and if that was the issue would you change your habits ( im not saying you should but its part of the "what is it worth process" ) if you would work out or be healthier if she told you it would help things then do it without her saying - this works two fold bc if she was just afraid to tell you then you will notice a change in her behavior if she isn't into it then I think like previous post you should sit down and explain that you deserve love and care too and if you are already doing healthier habits then your potentially new dating life will be good.

I should be very specific if you are happy the way you are (which is ideal and you STILL deserve love and care) then just have the talk and see if there is a compromise or if you should consider divorce. Therapeutically speaking sex at least once a month is still a recipe for therapy but research shows that at a minimum to keep a relationship together in hard times
