I don't know if I handled the sitch correctly but I am tired of the phone calls and text messages in front of me.
ABSOLUTELY you handled it correctly, Ashlee, and I'm damned proud of you.
It (calling and texting his girlfriend in front of you) was a boundary of personal integrity for you, right? It was sapping your dignity and your self-esteem, and it was extremely disrespectful to your marriage vows.
There's no reason why you SHOULDN'T have done what you did, and for the life of me I don't understand why more people don't do it.
You can be sure of one thing: he may be ANGRY at you right now (altho he'll get over it -- perhaps even very soon) . . . but he damned sure RESPECTED what you did.
