I heard a story about someone running into a school to shoot someone in a murder/suicide. I immediately knew that it was most likely a couple/ a relationship. Sure enough, was a man who killed his now ex wife and then himself. I figure he saw there were no other women out there, and wanted to end things so perhaps no one else could have her.

I'm still early RP, but I'm noticing aggression in myself as well when another man is speaking to any recent ex of mine. If this is the actual case for men when it comes to women/ relationships, do you have to move to locations where there are more women? How do you fight it when biology is making you become aggressive and territorial like fighting over water or food?
