"cost of having an addict out of my life = PRICELESS"
That quite basically sums it all up.
You already know what the right decision is to do....leave and never look back. He is actively using, he lies, he destroyed your property, manipulates, shows you no respect, and is in full blown active addiction. You deserve so much better than this chaotic, unfulfilling and stressful life. You even said yourself how much better you life was going when you went no contact. I loved how addicts say things like "I didn't want to bother you on your vacation" but yet they text/call anyway and bother you. It's like saying I won't call and then calling.
