I recently came across a 'love' letter from my first boyfriend back when I was about 17. When I moved in with my dp I packed up a load of random stuff and this was tucked into a book. I read through it and was sent back to a time where I was carefree and young. It was really nice to read back and remember this time from my youth. A lot has happened since this time and many people have come and gone and this letter just had so much happiness in and it was lovely to be reminded of some things.I am very happy with my family now and my dp is wonderful, reading this letter gave me no feelings for my ex but just the memories of things that happened around that time. One example is he gave reference to a joke he and my grandad shared and sadly my grandad has passed on now but hearing the joke made me so happy and brought back fond memories of my grandad. I have no intention of telling my dp about the letter as I don't think it would be right. Aibu to keep the letter for the memories? Or should I get rid of it. I don't want my dp to find it and think I'm hiding secrets as I 100% have no feelings for my ex anymore. This was many years ago now and I am thoroughly happy with my family.
