Take my own advice:

When you're angry with someone, especially someone you love, just ignore them for a bit — don't text them, call them, write stupid posts on blogs, reblog posts on Tumblr with hidden messages targeted at them — either sleep or just think about: the nice things they do for you, the sacrifices they make for you, things that made you so happy and so touched. It'll make you so much more grateful, and much better as a person.
