Husband left today...

I need support. My husband of 7 years(been together 12 years) decided today he’s done. I’m staying with my mom and we have a 2 year old together. I’m devastated. I feel like I have no one to turn to as he was always my comfort person. I can’t sleep and I’m just so alone and would love someone to talk to who has been through this. I can’t stop crying, I feel like I can’t move. My moms been caring for my son today because all I can do is cry. I have no idea how to move forward. I love his so much but he’s done. He said he thinks he will be happier without me. Which those words hurt more than anything else. I have gone above and beyond for this man. Given up so much. And he always told me no matter how bad it got he would work on our marriage. But now that’s out the window. I need hope. I can’t imagine getting passed this. Help!
