I am annoyed by my last break-up, not the least coz I am not sure I responded the way I should have. She said Goodbye in a text (mentioning her ex and other reasons) and I responded with "do what you want" and "ok, bye" and didn't answer her phone calls. But after that... I had a need to send some texts to the effect that she can go back to her Ex if it'll make her happy (which showed I was hurt.)

So what do you do? the correct response is "next", don't engage, move on etc. BUT we are humans, we have feeling, we need to express them - and so I find myself in a kind of Passive-Aggresive way - not showing clearly I am hurt, but acting on it - which is the worst I can do, being a recovering P-A person.
