bf sketchy...

i am pretty sure my bf watches his ex gfs only fans. he’s always on his phone, i saw him saving something on his laptop on a flash card... he always listens to music for hours and she’s always posting on her socials that she’s online... it wouldn’t matter to me as much but i’m pretty sure he doesn’t love me and is still in love w her. i’ve tried to communicate that w him but it turns into a fight. idk what to do anymore i want to leave
