Typical--Just--Typical

I'm going to make this a brief as possible.  After procrastinating about it for several days as I feared going into a bad tail-spin (as I usually do after seeing the EX) I emailed him saying that I wanted to go away back to my hometown to see my family for the weekend.  I contacted the him to see if you would watch our/my puppy as I can't take her with me and the rest of my family is also going back home.  Initially he said he couldn't do as he was going to his parents for the weekend. I asked him if he could take her with him (as we always brought her there when we visited).  He responded in an email saying that he'll pick her up Friday at 11am.  Therefore, ever since I found out, I have been mentioning his name to her to have her accustomed to his name again.  She was responding really well since I haven't said his name to her in 4 months.  

Well, I get an email Thursday night at 9:30pm saying: (this is the actual email)

I am really sorry for the short notice but my transportation arrangements have changed and I'm not able to take the puppy to my parents.

Again I am sorry.

I emailed him back to say--unless you are taking the bus to see your parents, I don't see why you can't take her with you.  Just put her in her cage and she'll be fine.  I also said that now I have to cancel all plans that I have made and do nothing all weekend because he can't take her. I even said to him that he should cancel his plans to watch her.  Obviously, there was no response back from him.  

I so want to seek revenge on him now and I have the tools and the ability to do it but.........what will I win out in the end other then him being totally humiliated and everyone knowing (including his family) his past and what he did to himself and ultimately us.

I won't because I just have to STOP!!!!
