Two Columns inverted on stack

Hi,

I’m attaching a picture of what I want.

I want two columns per row with 50% each, and two rows of that.

The thing is that when this goes mobile, the first row is OK: first text, then image.
But then in the second row, due to stacking, the two images are together. This hurts usability and understanding of my content.

Is there a way to change this, so the order is:

On big displays:
text-image
image-text

On small displays (stacked)
text-image
text-image

Thanks in advance,
