I'm sorry for you, really, but like you already said maybe it is better this way. I can also say from experience, if the sex doesn't work anymore, you first should try to improve it (what you did, but your ex didn't appreciate it at all) and then just let go... there are so many others out there and you shouldn't stick to one if it's not working, even though you loved her! But I'm kind of proud to hear that you found something what makes you feel better and really happy! And Exxxtrasmall is indeed an amazing site! I recently stumbled across a really good recording software called moviebox, the resolutions after recording are amazing, I can totally recommend it! Just take a look at their website, they have explained everything in detail there http://record-porn.com/en/How-to-record-and-download-videos-at-Exxxtrasmall
Hope this will help you & I wish you the best of luck!
