Dad takes advantage

[ginamom512]

So this is my friends situation:

Her and her ex don't follow the parenting plan anymore he now never shows up on time for visits he always says he is going to be there at 10am and he shows up two hrs later. He says he is dropping him back off at 6 and then he brings him back at 8:30pm. She is getting sick of it and is thinking of going back to the parenting plan because he has no consideration for anyone else. Opinions?
