I'm no longer physically attracted to my husband.
Why do you think you aren't physically attracted to him anymore?
Because the guy only knows how to eat and I'm fed up with it.
If you aren't attracted to your spouse, you need to work together with him to figure out how to change things. You should talk through your problems and see if you can come up with solutions that will make you both happy in your life together.
It's not like he needs to know. I'm sure I will fall in love with him again after he gets a nice body.
Even if your husband is already working to lose the weight, don't you think you should talk to him about how you feel? He is probably confused about why you aren't attracted to him and may just feel that you don't love him anymore.
