So me and my gf both are pretty young (18-20) (this is a throwaway account) We were on our way to pick up my newly done glasses I proceeded to park the car outside then a small family Of a M(probably 40s) & F(same as m) both were pretty heavy with their 2 children came in demanding I move my car as I parked on T spot (we will call the guy as R and women as T) so I told R I'm was just leaving then slight banter against T and my girlfriend occurs with my gf stating we did Nothing illegal they make a scene in the shop but soon leave(wile t is going crazy calling us educated illeterates) then as we exit the shop and go towards the car my gf starts recording their car then R goes ballistic telling her to delete all the video I tried to calm the situation but to no avil then he tried to snatch my gfs phone from her I then extend my hand to distance them. But he continues to use his physicality to over power me then T held my forearm forcefully and started scream that I touched her and R started recording (all while their children started to beg them to stop)

Then I tried open the cars door while T was forcing the door close then I distanced myself and during all this commotion I shit myself (I had diahreea if that helps) and my legs started shaking violently. I think nobody noticed tho after that some ppl started to gather around to calm the situation while my gf was telling me to get in the car. But I couldn't leave her alone outside the car. Then when ppl were holding them I opened the door for my gf we got in and left the scene. Then my gf starts berating me abt how I even when I tried to protect her (by extending my arm to stop them from approching her) made situation worse and that I was immature. She said I could have rotten in jail but she would be fine outside as ppl would cm to protect her. She then sent the video to her ex who goes to the gym aka strong and asked for his help and opinion on how to proceed.

IM ashamed of my self I'm not athletic. I'm weak, caused them to harass my gf. Idk what to do. any advice is good.

TL;DR I was confront and accused by physically large ppl and shat myself while failing to protect my gf
