Here is the truth: girls love compliments. They are very emotionally sensitive and tend to be more affectingly sophisticated to words than guys.
They react like little girls whenever some part of their astounding attributes (especially physical) are noticed and loose control whenever it happens. They need a lot of attention to satisfy their emotional needs and giving compliments can one of the best ways to do so.
The following might be considered romantic things to say to your girlfriend, but at the same time can also be poetic, funny, Philosophical, silly, weird, etc, but I prefer saying that they are sweet.

1- You’re so sweet. I might go diabetic

The above quotes can also be considered nice things to say to your girlfriend because they are not rude, but polite and stay within the limits of respect. If she becomes your wife one day, she might remember these quotes with a pleasant memory. Unfortunately, we men have little consideration at times for the emotional needs of our partner and forget that women love to hear similar sayings once a while.
