Thanks @nomad-magus

Today's issue is a very serious one. Many couples are facing with this problem, they are living under the same roof just like hostel mates and not lovers due to one disagreement or the other.

Little things like wanting to change your partner to who you want him or her to be can scatter the whole relationship because everyone want to be loved just the way they are.

If you don't love me for who I am, understand me for who I am not, then you don't love me at all.

While it is indeed possible to change a person, but you have to start by first change yourself first. If you show you love somebody deeply, their is absolute nothing he would not want to do to make you keep loving him. Your husband rejected your move to undergo some change in diet in other to for him loose some weight, because he has been suspecting your love for him for a while, he don't feel loved again, he don't want to commit himself to someone who doesn't care about his reality but only interested in his physic.

You have your choice to make here just like @nomad-magus advices, but if you stick to your husband, I know you can love him again if you allow. Think of his good side, build up the love for him from that angle and let the love radiate to other area of him, understand him for his bad side and be willing to work with him to correct the correctable, if he feels your love again, he will be more than willing to yield to your requests.

To help him loose weight, you can work generally on family diet, take more food that can help his condition as a family, even if you don't enjoy those foods yourself for now, endure it for some time, if he sees you are sacrificing this much just to proof your love for him, he will be willing to help out too.

Thanks @nomad-magus, you are the best of your kind.
