Desperate for Help with my marriage!

My husband of 5 years decided one day that he didnt love me anymore and that he's been unhappy with me for sometime.

I just dont understand because 2 weeks prior to this, he came up to me crying how he wanted to work things out with me and that he knew he walked away from God and wanted to be a better husband.

Now he is throwing everything we built away and splitting our family apart. He has already paid for his lawyer and has sent a complaint for divorce to the court.

I love him so much and this is killing me how my beloved husband has walked away from his faith and giving up on us.

I ask for God to please save this marriage and bring my husband back to Him.
