my dear SanitySeeker, I think you are beating up yourself for no good reason.....
first of all, you didn't do anything wrong....you had a romance, you found some old letters, which were way back that people were not hooked up with computer so much, now it's completely another era with all the technology and knowing everybody has access to computer, facebook, email instantly, so you tried to get in touch with him.....what the big deal?

I think he has to be ashamed of not answering your sweet email.....

However, that's computer and email.....It has happened to me so many times that people told me oh I emailed you and they were pretty hurt that I didn't replied them back....you know why I didn't answer them, because the email was going right into my junk email if it was not recognized the domain of the email.....there are millions of reasons why he didn't reply you back.....I think the last reason is him wanting to ignore you.....I do believe that he hasn't read the email yet....

Another example if it makes you feel better, I emailed my ex-huband when we were living together and that was an email begging him to work on our relationships.....he never replied me back and I never asked him why? this is the time that we used to live together.....then just couple of months ago, he finally replied back to the email.....same story, the email went to his junk emails and he never looked at his junk emails till five years later which was couple of months ago.....he was devastated in his email telling me how sorry he is for not reading that email and he was thinking that would have changed our life, but too late.....

So, I would not trust computer, email.....

another example is my mom who made our life hell, because my older sister who lives in England were not on facebook or skype talking to her for couple of days before mom goes to England to visit her.....mom was making all the stories that "oh she doesn't want me to go there and I would not go there and I won't tell her, I just change my ticket!"....that was insane....I told my sister and she said she has internet problem.....that's simple....just mom made her life and our life like a hell for couple of days....arggg....

Again.....I think you did a best move ever....I'm so proud of you and your encouragement.....I would have done the same and not having any regrets....that's a sign of being brave.....

If you need to rant about it, just write us back.....we all here to help....

with love
Marjan
