i saw this movie around 2007-2010

i know it was an old movie because of the quality and it was not in English

I remember parts of it

I remember the girl going back to stripping and the guy ( her old lover) saw a cut out board of her outside as an advertisement outside the place she was working at and he was really angry. Than at the end of the movie I remember them entering this building that had a pool. The pool was empty at first but it started filling up. The girl started walking away from the guy and the guy got mad so he swung one of the lights towards her and it hit her head and she knocked out inside the pool and she started bleeding . After he saw what he had done he swam towards her and hugged her while they both died while sinking in the pool and that’s how the movie ended
