Did I make the right decision ?

To be honest, I don't think your conflicting personalities should get in the way of a relationship.

This may seem a bit ridiculous to reference to, but if you've ever seen the movie Knocked Up, the two main characters are totally different. You may be able to relate to their situation, putting aside the plot.

Anyways, you shouldn't assume that your relationship is one that won't last. I believe you should give the relationship more time, and thought before actually breaking up with her. It may be something special.
