Okay! :P I did find an error, however slight.

1) My blood boils. If we weren't in such a public place, I'd probably yell after him. Luckily, I decide that making a scene in a packed supermarket probably isn't the smartest idea I'd ever head -(*had*) and continue my way to the check-out.

It does flow well, but you're right. a little slow for my tastes. It does however very clearly state the beginning of the road to recovery from a relationship. I'm sure it would be a better read to someone who needs to relate to someone about it.

Good job, overall. A very well done piece.
