My ex is single again, what would be the best way to contact her?

I sincerely think that that note was perfect. As I was reading it, I was picturing my boyfriend writing that to me and how after reading it, I would consider giving him another chance if he ever wrote anything as touching as that and if we were in the same position. I think any girl, with a heart, and an inkling of feeling left for their ex would love receiving that letter. And if it doesn't bring you two back together together, it would definitely put you both back on speaking terms. You have to remember though, even if you've found yourself and realize your mistakes and want to be a better person etc etc... she still may not have found herself. So if her response isn't what you want it to be, you should keep that in mind. Hope this helped
