How Can I Tell My Ex I Want To Fuck

Thx for following me through this journey with Covid .... And with my feelings for Matt.. He came over again to cook for us. No fucking potatoes! I'm sick of potatoes. Watching him interact with the kids and cooking... It all brought back memories. I'm hiding in my bathroom because I want him so bad. How do I tell him... Plz don't think I'm a slut.... Although maybe I am being slutty.... All I know is there are still feelings there and I want him...

Edit: No neither of us are in relationships. We got married super young. We were two dumb kids living in a fairy tale. Not financially stable at all. Real world hit us in the face quickly. We weren't ready but still decided to have kids. We broke our marriage because we didn't know what we were getting into. We had a talk about this over the phone. We've grown as people by ourselves. When I got Covid he truly brought out the feelings I had for him. He bought me 500 potatoes because he thought they cured Covid. He bought me Cheesecake factory and when I was so depressed and missed the kids, he put the kids on my lawn, with a sign about how much of a badass mom I am. We talked on the phone about what ended our marriage and how much we've grown. Just typing this out has made me realize how much I love him.
