Ex Fiancé..I need input

So I was engaged to my best friend/love of my life. He called it off a month before we were supposed to get married to basically sleep with other people. We lived together & had a cat & dog mind you. He told me I had to go to my parents house for a while so he could figure stuff out. He was still intimate with me & this went on for about 9 months after calling things off, on top of him telling me he loved me & we'll get married one day. A few months ago he kicked me out to move another girl into our apartment. I did everything for him & was always faithful. People keep telling me he'll come back at some point..
