How to make him or her addicted to you
Out of every item on this list, this life hack is probably the most reprehensible thing you could do. There’s no way you could justify doing this to someone else! Forcing an addiction to you by nicotine patches should be illegal if it isn’t already. That said, here’s how this trick works.
If you’re afraid that your SO is going to leave you for someone better (if you’re contemplating doing this, the bar isn’t set very high), stick a nicotine patch on them while they’re asleep and remove it before they wake up. When they leave you (good riddance), they’ll suffer from withdrawal and associate it with your absence.
