No, I never have. To be honest, I can even extend that to non-romantic relationships that have ended poorly. I don't bother. I've always been a strong believer that people like that will eventually get what they deserve. I don't need to waste any more of my life on scumbags like that than I already have. Bothering to plot some kind of revenge just feels like wasting more of my life on them rather than just moving on and realizing how much better off I am without them.
I'm actually proud of myself too from a recent incident. I actually had a recent a-hole from my not too distant past show back up to the group activity they used to attend of which I am a member. Last week, in fact. They hadn't been around for something like two years, but were back in the area and came for a visit. I could have done a million things. I could have glared daggers at them all night, I could have said something nasty, I could have told them to get the F out. ...But, I felt I deserved better than to let them bring that side out of me. ....All the same, though, THEY did not deserve a second of my life anymore, so I was NOT going to just sit there and play nice either. So, I just got up and left.
In my eyes, definitely the best option. To have sat there and just played nice would have been betraying myself in my personal view. YES, I believe in getting over bad things that happened to you and putting them in the past.... and with this particular person I have..... But I DO NOT agree that always means forgiving that person or forgetting. Some people do not deserve any place in your life, and don't even deserve to be treated like a human being. All the same, though maybe that scumbag WOULD have deserved anything nasty I may have done or said, I DO NOT deserve to dwell in those negative feelings. So, I did what was best for me, and was proud of myself for it.
On a side note, I've never believed in stuff like "psychics" but still find the concept entertaining. For a reasonable price, or if ever bored, I may actually consider visiting one just for the sake of entertainment. But, I don't for a millisecond believe that stuff.
Have you ever had a dream within a dream? For example, you are having a dream, then later within that same night you are writing in your journal about the dream you just had.... but even that is still a dream. (I've always found dreams to be a fascinating topic.)
