My ex feels it is ok to leave our dc age 2 and 4 in the care of his brother. He is generally a lovely guy but issues keep cropping up. Most recently he broke his hand punching a wall in anger during a row with his girlfriend. I believe he also kicked the bathroom door open when she locked herself in. Ex seems to feel it was just silliness. Is wall punching worrying? Does anyone else know a man who has done this and what sort of man is he? This guy is mid 30's, no kids, has a good job etc.
