Until he gives you that fucking ring!
Is your boyfriend dragging you around like a dirty old teddy bear he's had since birth but secretly wishes he could dispose of? It's time for you to show him how this is going to work.
Block him, but don't tell him.
Unblock him to tell him that you blocked him.
Block him again once you've told him you blocked him. Then say you'll unblock him if he threatens he'll block you.
Once you unblock him, block him again. Just for old time's sake.
Unblock him to see if he's said anything. Ask him to forgive you for blocking him. Then beg him to take you back.
