I have an answer to that question-all you have to do is know who her friends are, then know when they're together and when not---when you see she's no longer with her friend, run to where her friends are (female friends) then call one of them to a corner and privately tell her friend that she's a b*tch and an assh*le and she is a damn pr*stitute, just wait for about a second or more watch what will happen. Let's ur gf's friend name is tina. Hear what she'll tell you
TINA:you are such a fool, you said i'm a b*tch, hehe, your girlfriend is even our mama ontop, do you know she has slept with milions of men, everyone knows her, and she's just using you as her mere side-chick and she has extracted money from you-abeg bros go sit down, you be fool.
YOU: (at that moment you will know the difference between "love" and "maga"
[u] i'm a lady [\u] but i don't support cheating in a RELATIONSHIP.
