Husband (31 M) wants separation & possible divorce from me (35 F)

My husband (31 M) told me (35 F) he wants a divorce possibly but asked for a separation first. Next month we will be married for 2 years and November together for 5 years. He told me he doesn't feel that spark anymore and that he's out of love with me. Said it has nothing to do with me that I didn't do anything wrong, even went as far as saying I'm a great woman that anyone would be lucky to be with me, that this is hard for him because he knows this will hurt me and he has a lot of respect and love for me since I'm the Mother of his Son. He asked for the separation to make sure this is truly what his heart desires. Not only is this devastating for me but also confusing since he's been all over me the last month saying how much he loves me and how he's never loved a Woman the way he loves me, so this was very out of the blue. We financially can't actually separate as things are so expensive we need each other to survive. So we have separated as much as possible as we can within the same home. I just don't know how to separate from him when he is all I can think about because I love him. How do I just cut off feelings for him? How do I stop thinking about him? I feel like I’m being tormented and it's only day 3. Someone else must have gone through a similar situation to give me some kind of advice.
