Input: Text: i (32m) and my fiancee (29f) are moving in together into a new apartment. i have been living in my current apartment for almost 10 years now, so i have a lot of clutter that she's been helping me sort through and toss. 

while cleaning my bedroom closet, she found a victoria's secret bag with an (unused, as far as i can tell) set of lingerie that obviously wasn't hers, because she is a petite build and this was for a more full-figured woman. it almost certainly belonged to an ex who i haven't seen in 4 years, but i don't recall her ever wearing it. 

at some point, my ex stashed lingerie in my closet, presumably for a romantic night, and then either forgot about it or just never bothered picking it up after we broke up. and this was the lingerie my fiancee uncovered.

she *says* she believes my story, but she's been acting a little snippy and distant all morning. oops.

TIFU by cleaning my closet after not having cleaned it in 5 years.
