I am going crazy

LaTeX does not make what I want!!!
Look at the following Screenshot: I added the red point with Paint so you can see that the first interspace between the two symbols is smaller then the second interspace!
The Latex-Code is:
Code: Select all
$\{t | (\exists a \in Artikel \wedge \exists b \in Abteilung \wedge \exists f \in Filiale)(b.Nummer = a.Abteilung \wedge f.Stadt = Berlin)\}$\newline
$\{t | (\exists a \in Artikel \wedge \exists b \in Abteilung \wedge \exists f \in Filiale)(f.Stadt = Berlin \wedge b.Nummer = a.Abteilung)\}$
I want that Latex stops trying to squash a Text in one Line and that Latex skips spaces as in the picture!
How can I do that? Is there a package?
