i had a bf for 2.5 years then i told him i want to breakup he begged me to stay but still in the end we were over. i met with his parents, sisters, brother, cousins etc. he was so convinced that we were gonna be together forever. by the way the reason we broke up was he didn’t care about me being happy if im not beside him. he was toxic to the point that i felt like i had no emotions left being happy or being sad didn’t seem different to me. kind of numbness. then after we broke up he started posting pics with a girl which ive never seen or heard of. after a few weeks(2 months i guess) he posted a vid of them kissing and wrote down “i found a girl i’d catch a grenade for” (a trend on tiktok idk really). the funny thing is its impossible that i wouldn’t know if they met before cuz we tell each other everything. and it doesn’t make sense cuz i’ve known him for 5 years and he is someone who just isnt like that.

so im asking because my friends said he may be cheated on me cuz of the fact that he is so into this new one and he is not one to be so affectionate quickly. i dont know i didn’t mind till now but its bugging me. i need your help to tell me what could it be.
