Have u guys ever dated someone and now realise their red flags?

Like actually-- muhluhmuh experience I am so finding everyday new red flags abt my ex after that romanticisation wore off... I was a dumbass for always excusing it cus in my head "he can make mistakes" and I just hit my head in the wall... Like no wonder why my friends rooted for a break up like damn I loved him still. I was applying manhwa solution to my relationship which is funny cus im researching this and now I realise I have to interview myself
