So, they went to therapy.

However, after hashing things out there, the pair realized they needed to separate.

Next thing I know I’m…taking steroids, it was testosterone,” he said, viaPeople.

Then, when Haack got pregnant again, she had to go on strict bed rest.

“We were bickering about things [on-set], and we went home together,” she shared.

However, after they separated, Haack and El Moussa realized that they were better coworkers than spouses.

“We met at work, and we actually probably get along best at work,” she continued.

As it turns out, their sharing absolutelyeverythingmight not have been for the best.

“It was so stressful, and everyone was worried that it was going to explode.”

“In a lot of ways they just seemed wildly incompatible,” the insider said.

And more so, so did their daughter.

Haack and El Moussa’s oldest child, daughter Taylor, was obviously impacted by her parents' divorce.

But as it turns out, she’s handled it better than anyone could imagine.

It was big, but also telling.

If their daughter likes them better apart, then they truly must be happier that way.
