What was the dumbest thing your ex said when y'all were already broken up?

My ex and I were together for only 3 weeks probably more but I don't remember. Well once I broke it off (cheated on me) he texted me saying "he's so sorry and that we can have a baby". I was like wtf tripping. Then trying to pick me up to go out to eat while broken up. The whole time we dated all we did was fuck in his car 1 time his house then he'll drop me off. My dumbass being young thought he loved me but now that I think of it he was using me we never went on a real date to eat or movies or really anything. I learned my lesson for being so dumb and young.
