Hi all, my BF and I have been together for 2 years, he is 24 and I am 28. We are moving in together and I am 9 weeks pregnant (undecided if we are going to keep the baby).
Tonight after work I came to his to help him back, I found a box under the bed, it had a sticky label on it reading his name and his exes, clearly not his handwriting. He was with his ex from 16-20, long distance from 18-20 as she went away for uni. I asked what it was and he said "stuff", I asked if he wanted to keep it and what stuff (referencing the label). He said just bits and pieces and yes I want to keep it, he was quite defensive and he took it from me and sat it to the side.
I've been thinking about it all night and I woke up. I know this is an invasion of his privacy but I got up and took the box to the living room. I opened it, and it is filled with letters she sent him, little note books with polaroids of them on trips with him writing about the day beside it. Loose polaroids all with captions on the end (in her handwriting) saying things like "first date". There were some unsent letters from him to her, he dated them and they were handwritten and towards the end of the relationship. They are long and filled with details of his life, how much he misses her and loves her and can't wait to see her. Also random jewellery, book marks, tickets from events and all sorts. Also a whole little booklet just with pictures of her, clearly from dates or things they were at together but anyway.
I feel like I have never ever seen this side of him, he's very nonchalant, he doesn't really do big displays of affection, I don't expect it and really I find it all a bit cringe but it is making me feel odd, like he loved her more than he does me or something. Also the way he was so defensive when I found it and made it clear he wants to keep it, it isn't like he just forgot it existed.
I also don't really get the letters etc, like they were long distance yes, but it was 2018 and face time existed.
AIBU to feel weird about this? Should I tell him I looked or just leave it and move on? Or is he maybe not over her?
