I wouldn't text him again YES THIS IS ABOUT YOUR SON... don't make it about you reminding him about your son or about how angry you are that you have to keep reminding You should focus on you and you being there for your son. Your obligation is to your child..as hard as u it mat seem try not to hold onto anger and resentments free your heart so that it frees up some of your thoughts ..forgiveness isn't for other people its for ourselves..its our selfish side that doesn't want to forgve. In the end the result is astounding. Stay strong stay blessed stay focuses
