Is this emotional cheating

Problem/Goal: I (F 22) and my bf (M 23) had a conversation last time about cheating and na off ako nang sobra sa sagot niya (although hindi naman sakin pero sa past niya). Idk kung tamang sub ba tong pinagpostan ko pero I really need advice regardless.

For context, I really enjoy reading reddit stories on my free time and last time may nabasa ako sa ibang sub about sa “OA ba ako o may something in between sa bf ko and” kemberlu, and I scrolled through the comments for a whole 10 minutes. One comment caught my attention, it was from a guy saying na he can clearly tell na nagchecheat yung guy ni OP achuchu kasi he also went through that before except he only got tempted and never pumatol sa temptations. From that comment may nagreply sa kanya na kawawa naman daw yung gf or wife niya kasi natetempt pa rin siya, and from then nagkasagutan na sila sa comment section. So me, napaisip rin ako kung sino ba yung tama sa dalawang commenter.

Sakto my bf was with me at that time so I asked him kung natempt na rin ba siyang magcheat sa buong buhay niya, his answer caught me off guard kasi sobrang out of character nun para sakanya since u can clearly tell na he doesn’t really care about girls. Sabi niya, “Yes, sa ex ko nung may nakasama ako sa inuman na nilalandi ako”, pero nilinaw niya rin naman agad sakin na hindi siya pumatol pero natempt daw siya at that moment na pumatol kahit alam niyang may gf siya at that time.

attempts: Medyo in conflict yung utak ko sa sinagot niya given the history na sobrang naiinsecure ako sa ex niya dati pa since super flex siya sa girl before tapos sa akin ngayon parang tinatago ako for our entire 2 year relationship. Napaisip ako na if yung ex niya nga na maganda napag isipan niyang lokohin, paano pa kaya ako ngayon?

I know super babaw lang nito pero need ko parin ng advice on how to calm my thoughts and what to do please.
