DU....Stop! What good will come of it? Maybe short term vindictive evil happiness.....and in the long run....many bridges burned that will never be recrossed.
Take the emails...print them out....put them in a folder and tape it closed. Maybe someday you will have a use for them, but right now they represent nothing more than pain....pain for you that is. Almost like holding your arm over a lighter....you are the one causing the pain to happen...not the lighter.
Now stop this talk of wanting it to work out......Start working on you. All the rest is rubbish until you do that.
