Winter comes and you fall sick in bed with a high temperature. You ask your partner to do some things for you because of the situation you found yourself in but they seem distant and don't really care what happens to you - you might as well lie there sick forever. But when they fall sick and you take care of them they don't even appreciate what you're doing for them and they might even seem like they want to argue while you take care of them.
This indifference on their part is indicative that they are not interested to be in a relationship with you, they don't even care about you - it seems that they are in the relationship only out of habit. If you partner acts in this way then you should consider ending the relationship for good because nothing good will come out of it. You can never trust a person like that, which is why continuing to be in a relationship like that can only bring trouble in the future. It will be better for you to move on.
