What to do with old love letters?

I concur with the “burn them” contingent. You really don’t want your SO getting the wrong idea, MoodIndigo1’s post being exhibit A. You don’t need the letters to cherish your memory of your past love; you’ll still have those fond memories when those pieces of paper are gone.

Dude, you’re asking the wrong person the question in your OP. The fact that you haven’t told your wife about these letters and intend to hide them from her, send huge red flags up.

Not that you have some continuing emotional relationship going on with your ex…but that you’re not open enough with your wife that you feel that you need to hide them.

Do yourself a favor, and tell your wife that you came across these old letters and that you wanted her to know that your saving them for the timebeing, and hope that it doesn’t make her uncomfortable and reassure her as to why you are keeping them.
Also LOL at all the people that see some historical value of saving letters that were written 11 years ago.

They have huge historical significance…

… they were among the last letters ever written. I don’t think letters even exist anymore.

Have you been to counseling over these emotional issues? It is not unreasonable that people have past relationships that don’t work out. And that in the midst of those relationships that everything is the best it ever could be. I hope that you have come to terms with your husbands past relationships. It sounds like he has.
