Rant-My husband just left me

Without warning my husband completely blind sided me and told me he's leaving me today. We have been married for almost 4 years and together for 9. He didn't even have a real reason. He said he doesn't feel loved and doesn't want to have to "work" to make a marriage happy. He just wants happiness. I told him all relationships take work and he wouldn't hear it. I'm shocked and scared. My parents are letting me move in with them since he's moving in with his friends and I can't afford the lease on our house alone. I feel terrified and embarrassed. I'm now going to have to tell people he's no longer in the picture when they ask about him again. This baby wasn't planned but was very wanted. He still stood by that. But said he'll only want to see the kid now and then. Just. Idiocy. I don't understand why it's happening. Why decide to leave when I'm 13 weeks pregnant of all times...😞
