How do I make my boyfriend miss me?

By baking him a delicious cake, then eating the entire thing in front of him without sharing

Sometimes a little me time is welcome

keep giving him money...and don't let him work

Break up with him.

Hmmm...there's an old song from back in the 60s that I remember:
How can I Miss You If You Don't Go Away?
That might work.

I'll suppress my unhelpful comment in the name of good taste.

He will no need to force it.You should miss him too

Blow jobs.
