My boyfriend and I (59 and 48 respectively) occasionally go to a small pub round the corner from his house. It's a great place and he's known the landlady for years so we don't want to stop going.
There is a woman who is always there who is 30. She's gay and, at the weekend was quite obviously flirting with him and told me she is 'smitten' but that I'm safe because she's gay 
I know it sounds pathetic but it's just irritating!
Until this declaration at the weekend, she had been content to just stand in front of him, wherever we are sitting, and twerk (I know - classy) and jiggle her breasts in his direction throughout the evening but this weekend, she was intruding on our night out.
I find her irritating. He finds her irritating. It means that an otherwise very enjoyable night out is tainted by this because neither of us wants to sit having a chat or chatting to others with her acting out in front of us.
It's not really serious enough to escalate by 'addressing' it, I just need a comeback for when she's saying stuff to me about him!
Any suggestions..?
