Do you normally order diet? If not, that would be kind of a jerk move on his part. I know most people seem quick to defend him, but depending on your past with him and what he knows about you, comments like that can cut.

I need more info to decide properly. Did he say diet because he thinks you need to slim down, or because you usually drink diet or are you diabetic or something?

does fml moderators actually read these wtf???

You need to stop worrying. Your boyfriend may be wondering if you would want diet or a normal coke, not because he thinks you need to diet, but because he might not be sure about your preference. (I know people who prefer diet coke because of the taste)

Diet products are actually pretty bad for you.

I like the taste of Diet Coke better.

No, Diet Coke is a lot worse

what a jerk. and diet is even worse for you since it's fake sugar and chemicals that is what makes it low calorie.

do not take it personal,last thing you want to make a problem about diet soda.

I think you might be being a bit sensitive... My boyfriend asks the same thing - because he knows I prefer it.
