I saw my boyfriend speaking to his ex girlfriend at the store. The way she looked at him made me so mad.

Oh man, I would have been really frustrated. Does she know he is dating you now?

Of course, our town is so small. However, I could be letting my imagination get in the way. Gosh, her smirk is what made it worse.
