Hi there diva and welcome to SR.
Reading the sticky or power posts at the top of this forum is a great way to start. Check out those at the top of the nar-anon one too - there's some really good stuff there too.
I think you handled that call pretty well. He was asking your permission and you refused to give him that. The insults came from that refusal and is extremely common.
Why not start a new thread and introduce yourself? There is loads of help and support on here and you can guarantee that someone will have been in the same situation as you.
Looking forward to getting to know you.
Love
Minnie
