Help me with a new perspective on this

r/

So my bf (30M) and I (30F) have been dating for almost 8 years now, so we know each other pretty well. Last night I had a weird situation and I cant make up my mind where I stand

I thought I was all in for some white lies, turns out this bothers me

Some days ago I noticed an anime opened in his pc. Didnt think much of it we all are curious. But now that I think he insisted I move and watch the website on my pc

Last night we had scheduled a movie. He had downloaded two so I had to pick. I asked him as he was watching videos before I had the laptop and he told me go to downloads.

Force of habit I pressed ctrl+h. Mind you the laptop is used only to watch movies/anime and youtube together.
On history I noticed the same anime

So I asked if he was watching an anime without me, maybe he started it when he was in his hometown a couple of days?
He said no.

Back and forth, he has clicked on this anime on every episode for the last month( together with this was another anime but whatever didnt bring this up)

Also one of the days he had clicked was excactly when I was not around checked with my period calendar (also didnt mention this to him)
First he just checked this one out of curiosity, then other episodes came up, then he just saw couple of mins

So now that I think, he intended to watch the episode while I was doing my hair.

He stands firm that im wrong and he is not lying. He goes to say that im lying and this was all on purpose

He also said sth along the lines: If you ever think I dont love you a lot think of this situation as according to him im nosy, ask a lot, gove no space etc

And he is right. I tend to be like that

I also feel like that at times. If im super in the mood and want to hug and kiss and have sex and I think he is being sneaky is a HUGE turn off for me.

And the point is that this is such a stupid thing to lie about (maybe im wrong and he is not lying but everything points at this in my opinion)

But since this is harmless maybe I just have just let it go? Maybe he was feeling uneasy to share that? Idk I also have things I dont want to share…like if he gets up now and asks me what im doing ill prolly tell taking my mind off which is a lie

But this bothers me so muchh

He said he loves me before sleeping which is nice considering he got annoyed, and I cant also take my mind off of all the sex I coudve get tonight -_-

TL;DR: Im bothered by a harmless white lie, and its impacting every little desire I have left
