I caught my best friend's wife with another man and I never told am

I catch my best friend's wife with another man for Lekki last month. She no see me, but I see everything. The way she dey laugh with the guy, the way he dey hold her hand. E pain me because my friend dey hustle day and night for this guy.

I never tell am. I dey ask myself every day, na my business? If I talk, e fit break their marriage. If I no talk, e fit continue. My friend go still dey spend money on her, dey suffer, and she dey enjoy with another man.

Since that day, I no dey see my friend the same way. I dey smile with am but inside I dey carry this heavy load. God when? Some things, you no fit just talk.
