Why ex invited me to spend the day at his house?

He said it would be convenient to me to do my studying at his house. What's going on?

I too would be thinking booty call but this will be a daytime visit. Also he is quite proud and would rather just jerk off than ask for sex, especially from me, even though I know he loved my blowjobs.
