My God, When I think back to some of crazy and yes immature stuff I did even AFTER I had kids, It makes me shutter.
Going was a bad disicion, you learned that. Everything after that doesn't matter.
Except NOW - it's time to be the bigger person and move forward.
Mail him (drop of his phone and stuff) That is it.
Keep your diginity, don't get wrapped up in having to get revenge (the burning thing).
You will only feel bad if you stoop to his level.
Keep you head up high and keep learning and growing.
BE THE BIGGER PERSON SWEETIE!
