My(19f) boyfriend(21m) still has nudes of his first love.

Hi all. My boyfriend and I have been dating for five months now, so our relationship is still fairly new. He's a great person and super attentive to my needs and I have little to complain about him.

However, he has an ex who I'm pretty sure is his first love. They dated for three years and broke up just over a year ago because they had to go long-distance. I've been iffy about his feelings for her since the beginning of our relationship but didn't want to blow anything out of proportion since I understand that feelings don't just fade away. He's also reassured me several times that he has no emotional attachment to her anymore and is no longer in love with her.

But just today while we were hanging out, we were going through each other's photos as a cute bonding moment. I went into his "hidden" album just to look at the photos that I've sent him and stuff and happened to see two videos of him and his ex making love. I quickly scrolled away and gave him his phone back as I didn't want to intrude his or her privacy like that. I let him know that I saw it and casually asked him if he still uses the videos. He said he doesn't as he doesn't feel anything when watching it.

At first, I thought that they were just in his camera roll from use after his breakup and he never really got around to deleting them. But after thinking about it more, it seems weird to me that after 3 years together he would only have two videos? He definitely deleted the majority of them, but then why save just those two? And I've sent him my own photos and he's taken videos of us before too which he puts in the album and has used before. Wouldn't he see those two videos while scrolling through our photos and think about deleting them?

I talked to him after and he said that he'd delete them, but I can't help but feel a bit off about it. Am I reading too much into the situation or overstepping my boundaries? We've only been dating for five months too so is it too early to expect that level of commitment to each other? I don't know what to think and don't wanna make this a bigger deal than it has to be. pls help!
