My bf said I embarrassed him today

Just a throwaway account and a rant.

I am crying as im typing this and I just wanted an outlet to vent. So me, my bf and our friend circle, we were going somewhere via metro. In the station, my metro card didn't work. All my folks were already on the other side so the guards opened the middle gate for me (the one they open for people to pass through, if their cards are not working). Now that gate was stuck and so it opened just a little.

I am a petite person so i easily slid through. And idk what i was thinking but i exclaimed, "Oh i got through haha". Now my bf pulled me aside and told me, "Thats not a flex". I was so confused rest of the journey why he said that to me.

Reaching back, i asked him what he meant by that. And he said i embarrassed him by showing the whole world how i have no ass and that was nothing to laugh about and I could have waited till the guard tried to unjam the gate and opened it a bit more. I couldn't say anything back. I just left and I am crying uncontrollably since then.

Ik I am not a curvy person. I eat a lot but nothing happens. I can start going to gym but life is hectic. Idk what im blabbering, leave it.
