Was she pregnant ?

I think that at the and of the movie when Cordoba talks with Stelios about how he said that he was OK with her being pregnant or smoething like that,that she already was pregnant with his child but didnt tell him because of his reaction in their last conversation...

I think that she realized that he wont ever take her back because she cheated on him with his best friend and thats why she was going back to Germany to maybe raise her baby alone because she didnt want to get him back with the "baby card"...

At least thats how I understood their last conversation and her talking about him being ok with her geting pregnant...
