See you after the breakup. How can I ask for the last time? He will say yes.

You said you were going abroad, why not invite a large group of friends to have a farewell party or something? Remember to invite friends you all know and let them beat around the bush. I don't think he will be embarrassed by not coming. In short, try to invite him to the farewell party, and then ask his friends to help. Drink as much as you can, don't get too drunk, stay awake and hug your friends with alcohol. Of course, the point is him.
