Marriage help

My husband of 10 years told me a few weeks ago he no longer is in love with me. Hes felt this way for years apparently. We tried to make it work, and the other day he told me he still felt the same way. He told me we should separate (I still live in the house, and take care of our two kids.) He told me he will always love me and we will always be best friends. I've been with him since I was 17, and I'm 32 now. I'm terrified of being on my own and starting over. Hes all I know. He also told me we wont make things official (divorce wise), unless I find someone that gives me what I want and makes me happy. I honestly dont know what to do. Do I find a place of my own? Do I keep living with him and the kids? Is there a chance he may love me again? Help me please
