How do you forgive your boyfriend?

You forgive your boyfriend by realizing that a 'boyfriend' is just a friend with extra obligations assigned by you at the suggestion of outside forces (culture, society, advertising, etc) and that perhaps your motivations for being angry are not really your own.

Much of the social discord in our society is caused by unrealistic demands placed upon our loved ones that were suggested by people only interested in controlling or profiting off of a divided populace.

Monogamy at its core is a system of passive human ownership. Jealousy is an emotional response triggered by the loss of, or attack upon, the powers associated with that ownership.

Examine why you were mad at him in the first place, and ask yourself, are you actually mad at something he did, or do you merely recognize that according to TV and the like, you're supposed to be mad.

9 of ten times anger of any sort is trivial, unjustified, and media inspired. They want us angry at each other to keep us from being angry at them.

But then again, maybe you shouldn't, maybe you're better off. You never know. :)
