Thank you for your replies

I cant believe someone in the world was in this same situation as me. Don't feel quite alone on that front now yay!
I've made up my mind, I am gonna go, this band really don't play live often, and why should I miss out just because of an ass and his sheep!

I know all your advise is actually the most wise thing to do so I do appreciate it.
Plus I kind of have to go really because ex stupidly told me to get a spare ticket incase any of 'my friends' wanted to go but non of my friends like that music so he found one of his mates that did so it wasn't such a wasteful ticket.
So I guess just a case of grin and bare it.
Also scared because of some health issues I'm gonna faint like I did last time at a 'standing' gig. EXBPD having 0% empathy, always thinks I'm either lieing or wanting attention or something but meh whatever.
