While in Mexico City a drug addict approached me and my girlfriend. She was clearly uncomfortable and he kept bothering us. He wouldn't leave us alone and I responded to his rudeness with being rude. If he would have touched us, I would have fought even though I'm not a violent person.

Know the country before going there, maybe don't go there?
Bring whatever is legal to defend yourself and others, but also know how to use it beyond showing it to the bad guys.
If fighting is sure to result in victory then you must fight!
Situational awareness can generally keep you safer than raw firepower.
Make sure your gf knows how to use the defenses too, especially if they try to split you up.

best to find out the country laws and how to defend yourself legally there. Also if you or your GF can carry something like a pepper spray, then have that and use it, without getting into a physical altercation, most of the time when it gets physical, both you and the other person will end up in trouble, irrelevant what the other person did

maybe dont travel to mexico city? just go to yucatan like a normal tourist?

Ah, tropical fruit. Like pineapple. Or the dragonfruit I have in the kitchen. Very funny.

Have you considered constructing a giant robot that can keep you safe? I saw this in a cartoon once.

If it's a fist fight I can probably take them out, mexicans are usually shorter.
