What do I do

I’m 10 weeks pregnant, my husband has now told me he has lost love for me and doesn’t want to be here

He makes all the money, he owns his own company. I work PRN at a doctors office I don’t make enough to raise my 3 year old and a soon to be new born alone I can’t do it alone I have so much love for him I’m unsure what I’ve done to him to make him lose love for me I’m so broken right now
