I'm going to make my boyfriend sugarfree salad dressing
Do you think he'd like the dressing to be sugar free?
I think he likes non fat things, thats why I'm going to change other stuff too
It's good to be considerate of your partner's food preferences when preparing a meal. Otherwise they may not feel like their feelings or tastes are being considered when it comes to the meals they prefer.
It's not good to try and make a whole meal just for myself, I'm going to ask what he wants to eat too.
I'm glad that you are taking your partner's needs into account. I'm sure he appreciates everything you are doing for him.
