Won't be the last time something like this happens unfortunately. Getting involved and obsessed with a prossie never ends well.
Being rich may help to pay the bills and put a roof over your head but it doesn't equate to happiness. There are so many rich people not happy or content with their lives as they're missing that emotional connection with someone. Going after a prossie will only end badly.
With such a large punting pot I'd travel the world picking up all the hot women in top bars and clubs. Just enjoy yourself.
