You have my sympathy, wading through the shite is no fun and to come close to satisfaction and have it pulled away must be very frustrating for you. I was in a not dissimilar situation this time last year, but had a fucking great time being single for a year ( not interested in another relationship then ), one of the best years I've had ever in fact. I think spending time out of relationships is underated and often very healthy and you never do know when you will meet REAL people who will treat you how you want to be treated. Keep your chin up.
