WTF!! How do I get over someone

My ex and I are still living together. Literally just broke up about 2 weeks ago and he’s already hanging out with some other girl?! Literally after eating my ass and pounding me 3 nights in a fucking row. I’m livid and so fucking hurt. We have kids together and have been together since high school and he’s moving on this fast. How do you get over someone you’re still so in love with?!

I’m hurt you guys. Bad. Our kids and I are at my sisters house for now. It wasn’t ideal for me to just leave the house. I don’t have a car, no money or job because I’ve been a stay at home mom. And my daughter was in school with special needs. I thought it was okay for us to still be there with him so he could still see the kids and help with drs appointments and other stuff. I’m really going through a lot right now.
