Confused

I'm confused out of this world,
One simple word turns everything bad,
The one who supposedly dedicated her life to me,
Has now broken my heart,

To my friends i ask,
Should i leave or stay,
Many days I cry in confusion,
Sleepless nights and endless days,

Making this harsh reality so much worse,
Thinking of her lips touching another's,
Having passionate love with another man,
In which is my best-friend,

The two people I would die for,
Betray my love in my house,
What should I say,
What should I do,

DAMN,I'M JUST SO CONFUSED!
