Good for you for escapeing. OCD is obsessive compulsive disorders. Obsesively washing your hands 50 or so times a day, checking that the door is locked repeatedly and not just a few times, like enough to make you late for work because you are checking the door a million times, super organized, ex. closets separated by color or short sleeve shirts, long sleeved shirts, jeans, pants, belts, ties, just very controlled. Lots of OCD folks organize the inside of there cabinets w/ boxes going from tallest to shortest. These people are often very ridged about certain things, the min's on a clock, how long food takes to cook ex 20 min exactly not a second more or less even if the food is burning or not fully cooked. My H had me and the kids pick up dirty gravel out of the driveway and pick up blades of hay from in the yard, pick up grass seeds &hey seeds off of the gravel. These issues were very real to him and caused a great amount of agitation if left undone.

Your son's father sounds like a narcissistic. Meaning he only thinks of himself and how the world relates to him and what it and everything in it has to offer him. Just a thought but since I don't know the man it's hard for me to say.
