Don't take it personal, it's only your Sag being real...
Sagittarius has firm ideas about everything - work, politics, and romance. You can't pin one down or force one to love you. They know what they want. They also know if they're in love.
There's no mystery to figuring out where you stand - Sag will tell you! Just like he'll say your butt looks big in those pants, or she'll say the joke you told at the party was stupid.
This sign can't lie, and Sag certainly isn't going to start practicing with those three little words. Conversely, if the thrill is gone, your Sag will be, too. No lame excuse, no apology.
