ok i guess TS probaly punched that guy, not because its for the
girl. its probaly for himself. punches were thrown for mistrusting
that guy.
TS was probaly also gentlemen enough not to lay a finger on the
girl, though a bytch she was. ( if there's really smth btwn her and
tt guy tt is. ) perhaps TS was abit rash at that moment and didn't
really know the correct action to take and thus, the punches
came.
no point crying over spilt milk right. nothing can be done to
revert back. giving him advices on what he shouldn't do at that
point of time wouldn't really help. guess what we can do is advice
him on what he should do now.
and what i can advice for you to do, is probaly just go straight
and tell him in the face that you're sorry for throwing the punches
at him, and try to dig out reasons for him coming out of your gf
house.
1) if its really nothing, tts if you still are able to trust him,
sincerely apologise and just pray he forgives you and lightens the
charges.
2) if he's really eye-ing for your gf, tell him that you felt so
disappointed trusting him as a friend/buddy when he actually does
this kinda thing to you. and afterwhich, start badmouthing him to
all your friends and his friends
