Husband recently decided to separate from me

So although he loves me, my husband wants to take a break from our marriage . We're now leaving separately . I'm not taking it very well, it's like 13 years down the drain. He says he still wants to be friends since we act more like friends than a married couple now. The family ( both sides ) wants us to try and work it out. But how do I work on something like this, when he's the one that doesn't wanna be with me anymore?
