My T has never cursed at me in anger/frustration. He has used swear words, usually after I have already introduced them (if I say, "I'm in deep s***" he might ask "what kind of s***?" to make up an example), but that's cursing with me, not at me.

As far as whether the OP's T was out of line, I feel like so much depends on tone, body language, context that I don't know whether the T's in the wrong or not. But if you (OP) found it offensive or insulting, of course that is something to bring up and deal with.
