I'd advise method b. Just be sure not to get mad, and be willing to discuss the issue reasonably, even if the other person gets angry at you. The sucess of this will depend on the person and their tolerance, but at the very least you're showing that you care enough about them and your relationship to talk about it. Often people you try it on will get angry initially, but I've found that it's usually better in the long run. If they don't care enough about you to put up with you talking about it, then they don't deserve your love.
If you think you can forget it, and the other member of the relationship seems to be willing to continue in a way that you're happy with, then maybe you should try that. But if you're hurt enough to be asking us about this, then I'd imagine that you won't be able to forget it and treat him or her the same way without talking about it. Plus, most loved ones expect honesty from you, even if it hurts them.
