Rapid Change

It's been 2 weeks since my life turned upside down. In the middle of the night my fiancé (been with for 5 and a half years, lived together for 3 years and engaged for a year and a half) told me he didn't love me. It devastated me and broke my heart. He promised to give me a week, to see if we could bring back the love but the next night he said we wanted space and asked me to leave for a week. I agreed but before the week was over he changed his mind again and told me this would be permanent. We have 4 pets together and a car, we built a life together and he ended it without giving me a say. When we decided to move in together, get pets, get a car... etc we always promised to never walk away. But he did, completely out of the blue. I lost everything in my life that was important to me, he was the love of my life, my best friend, my partner in all things. I lost my home, my pets, even a great friend who took his side. We're still trying to be friends for the sake of the pets and mutual friends but it's very hard, not because I still love him but because he's not the same man I fell in love with. He's mean, and sometimes cruel. He doesn't care about me at all and he is reckless. Every day it gets easier because I don't recognize him. Now the only thing I miss is the relationship and partnership, coming home to someone who loves you, someone to hold you and kiss you when you've had a bad day. I'm not even really looking for advice, I really just needed to get this off my chest.
