Don't hook up with a girl on February 13th.
Don't listen to him, guys. The girl will want to date you forever. Fall in love, make babies, spend every second together. But ladies, don't tell him that.
Don't use another guy to make your man jealous.
Psh. Whatever. That totally works. I recommend a soulful blue collar black guy. You'll have your guy doing one-handed push-ups trying to impress you in no time.
Do dump her if you get a better job and know you can do better.
If he does this, Do fake a pregnancy.
