When do you use con tu, con yo, contigo, and conmigo? Please give an actual answer. If you don't know the answer please fork off. Have some pancakes instead.
They translate to with you, with me, with you, and with me, so a sentence you would use them in would be something like "Want to go get ice-cream with me?" meaning "¿Quieres ir a tomar un helado conmigo?"
