Sounds like your gf is just a jerk, you don't need to have personal experience with tinnitus to "understand" it or be polite and make accommodations for it.

I have great hearing. My mother in law is very hard of hearing and it's the same way - unless you're actively engaging in a face to face conversation with her it doesn't 'click' that you're talking to her until mid sentence. It's so just not a big deal - I learned really early (like the first day I met her) that if I want to say something to her I just have to pause and make sure I have her attention first. I couldn't imagine acting like your girlfriend if I forgot to get her attention first.
