Single mama getting back on her feet

Hello friends, I am currently finding myself very suddenly back to being a single mama of my two amazing girls, after 6 years and an engagement, in a matter of two weeks, everything has changed. I am still reeling from what happened, my spouse woke up one day and didn't want our little family anymore, to the point of just acting like the girls and I no longer existed and already being on dating sites before I could even get myself and the girls out of the house. I'm not going to be able to make ends meet for March, I'm at my absolute wits end, this is the last place I ever wanted to be asking for help. But I don't know what else to do. I love you all, and appreciate any help. ❤️
