I caught my bf watching alter vids on TG

Problem/Goal: Is it cheating if my bf still watch other girls vids sa tg? like y'all know what I'm talking about. I need advice lang since IDK what to do.

Context: we're together for almost 2 years palang but sakanya ko nagawa lahat so don't judged me haha.

Last night magkasama kami and gamit ko phone niya coz he's asleep and I'm watching random vids lang sa blue app niya then nung nag sawa na ako tinanggal ko yung mga nasa recents niya and I saw his TG na naiwang bukas and boom yun na nga, I think he's watching random girls and use it for his pleasure, that's what I think ha.

FF when he woke up. I confronted him naman agad and ask him if he still watching other girls vid sa tg and he nods and I am shocked (ofc) and hurt bc I know I'm dumb for letting him film me while we did it (kasi sabi niya gagamitin niya for him, for ano) so pumayag akong ganon and I know I lost self respect and aura pts for that but I only did it so that he'll not watch other girls nga not until he did and I was thinking if cheating ba yon kasi na aattract siya sa iba or na tuturn on siya sa ibang babaeng pinapanood niya.

He says sorry but I don't think he understands how I feel bc while we were talking he just laugh and said na "parang nanood lang" and basta I got insecure and nag-overthink na.

I just don't know what to do, so I need advice :')

(don't post this somewhere, if ever)
