Thanks guys, your support means so much to me right now, I don't have a lot of RL friends that I didn't share with him so I am struggling to vent anywhere as people are all just "but he was so lovely I can't believe it?!". Which is true but not exactly helpful!!!
Yeah Quim Every cloud... 
We were supposed to be going for dinner and I had booked a reservation using his number, I don't know why just couldn't think of my own at the time I think. He was sorting something upstairs and I went to check the reservation details and it was just all there. Messages, pictures the whole nine yards, new "training" at work was not training! Been going on for bloody months... Kicked him out on Friday night and then told my mum, unplugged the phone and internet and just came up with a plan.
I am glad I am moving in the next few weeks because it will give me a real fresh start. His mother has been totally amazing, and she can barely look at him, my own mother has been a PITA and keeps flapping about and making it about her.
We had been together for 6 and half years and I thought everything was more or less perfect, both families have been expecting a proposal for the last year or so. We met at uni when we were 18 and 19, he had his flaws but I thought he was a genuinely "nice guy" clearly I was wrong. He begged me to take him back but I don't want to, I feel like I have been punched in the gut and I have wasted the last 6 years on a total knob.
I waver between angry, sad, and bloody frustrated that I have to sort out splitting our belongings and savings and all the other admin stuff.
P.S. her name is "Claire" and she sounds like a total slag very mature
