Wendylon, I hear your frustration. Have you thought about starting conversations about what you want to see in the M? Remember, it's not about how you want him to change, but what you need in the M to be happy.
So far, it seems your biggest disappointments are with: 1) His lack of commitment to goals 2) Lack of attention 3) Unreliability
How can you translate this into actionable items that he can take so you can be happy? Think about this. And keep focusing on what you like about him, okay? Don't lose sight of this.
BTW, good idea to let him go on the trip with S13. Keep the 180's going, and soon enough, you'll start witnessing his own 180's.
