I sympathise with you, and if she tried to attack you physically earlier on, she should have been removed then. (Any idea why she wasn't?) But I stick to what I say about removing you later on: if you look like you had to be held back then even in a Naafi bar a publican is well within his rights chucking you out, regardless of anything that might have happened previously.
There's no answer to this really except never even look as if you're going to be violent in a bar. No harm in having a quiet word with them - when you're stone cold sober - and making the point that you're entitled to drink without being attacked, by anyone of either sex.
