Hey Bright! That's great you aren't getting the knot in your stomach or racing heart with h coming to town. That's a good feeling to not be phased. Good for you.
His "partying" will only be fun for awhile, I'm sure. Once he realizes that it really isn't fulfilling anything for him. It's an avoidance. And boy do they love to avoid. Numb. Disengage. Hide. It's one in the same.
But you, my dear, are doing so well. I'm happy you are finding your way, Bright. Kudos to you! Cheers!
