When I'm hurt, I want others to get hurt too

Ouch!

What do you feel when someone hurt your feelings? For me I have this bad habit where I like to hurt back the person that's been hurting me, I know, inappropriate right.

But I'm not talking about small kinda hurting here, most of the time it was because that person hurt my feelings so much that I feel he or she deserved to be hurt as well.

One time there's this person who promised to spend time with me but eventually bailed on me for other people, I was hurt because I've freakin spend like tons of money and time just to make sure I was available for that person but end up spending the time alone, the person even give me like the most unacceptable reason.

So what do I do? Of course I get even and end up hurting that person's feeling.

Am I a bad guy? I think so...

Am I selfish? Not really, because that person should think about the consequences before getting me hurt.
