Just don't be a idiot and fight. I've never lost a fight (had several over the years) but I've never instigated the fight and always tried to leave my opponent a way to back down without losing too much face. I did once get headbutted by some moron (he was mid 30's and I was 18 at the time) which I just walked away from as he had about 5 of his mates around him (yeah, real hard man). Fighting will not solve the route cause of the problem and ultimately can lead to things escalating (like some nob head 30 year old having his car tyres slashed for instance).
I highly doubt the ex will have the balls to follow up his threat by the way. Never fear the ones who mouth off, it's the doers you have to really worry about.
