His behavior was very abusive and chauvinistic, as he said, "A woman's place" was to take care of the children and obey the husband.
On a walk during Observation, he tried explaining that Morgan could dress like "a decent woman" by not showing cleavage or wearing tight pants, which he felt was dressed for a slut or whore (feelings he only confessed when prodded by Jo). This led to Morgan crying about Phil calling her a slut and a whore for dressing in skinny jeans and showing cleavage, which really didn't seem to be Phil's intent. It was very clear that Phil's concern was making sure boys did not take advantage of Morgan or think they could use her in any demeaning way based on her dress.
Jo showed Phil how his harsh comments were like darts in the face by making him throw darts at pictures of his children's faces. He understood the point and felt bad about all he had done to damage his children's self-esteem.
He also learned how much he had damaged Debbra's trust when Jo had him and Debbra do a trust exercise at a local gym. Debbra refused several times to just drop backward into his arms. Then Phil was told he would do the trust exercise into Debbra's arms, but instead free-fell into a pile of foam. He was shocked and terrified, and then understood the fear and insecurity Debbra felt in trying to trust Phil. He has posts from December 2017, so that confirms that he did not kill Debbra, and that he did not get sent to prison.
He was 41 years old when he appeared on Supernanny and is now 50 in 2017.
