Does it hurt oneself, when you pretend to NOT be hurt, when you really are?

It makes perfect sense. I've been there, a lot of people have. I've been there with an ex, and I acted aloof and he actually came back - only to hurt me again. I regret holding it in and not letting him know that he was such a jerk, but I'm the kind that holds her head high and moves on. But he should know he hurt me. And your ex HAS to know she hurt you. I don't like the drama, and if you don't either, just let her know simply and cooly. No drama, no games. "I just think you should know that what you did hurt." Let her know it hurt, but also that you don't want her back. When I'm hurt (by a guy or even friends) I shut up and try not to ruin stuff. But it's wrong. Speak up, let it out. It's the best, trust me.
