I'm leaving the man I've been with for 2 years

I met him and fell in love. But he has changed so much over two years he's almost a different person. 
There's no trust because he breaks it. I moved in with him an hour away from my home. I have a job. The reason I haven't left yet is because of the hassle of moving back and me loving my job. Can anyone help me a little to go through with this. I just can't give him anymore chances. But I know I will unless I have someone telling me I'm making the right decision. Thank you!!
