I should just let it be and just let my actions speak for themselves and let him go for a while
That's what seems to work with him (aka Vegas) so do it.
Get on with your life and let him get on with his. He's lived with you for more than 10 years, he knows what you're really like, and he's probably as surprised as you are about whatever it was that happened because I'm guessing it was pretty out of character?
I like what your therapist said about spoilt brat vis-a-vis scared little girl. That's the other problem with girls like us - we are very hard on ourselves and each other. We need to give ourselves a break sometimes.
