What Was I THINKING?

Have you ever looked back at some of the people you've dated, and say to yourself "WHAT THE HELL WAS I THINKING"? I think we all have that one EX that we shed a few tears over lol, and now when  you see them, your like i can't believe i actually told him/her I LOVE YOU, better yet how did i ever shed a few tears over THAT.0_o. Even though i've NEVER EVER done COKE, OR CRACK  in my life, But after dating some of the men i've dated i had to be on something,lol! Does anyone else ever question their past relationships? I'm telling you it's a crazy feeling when your out with your new partner, and you run into your EX, and your new partner is looking at you like you have some explaining to do! 0_o, And your like WHAT? That's when i was at my really low point in LIFE, and He/OR SHE was there for me...LMAO o_o
