I am not the one who got the short end of the stick

[SHORT FLASHBACK]

"I need to know the preview, and I'll make it happen. Maybe even better."

If there was a lesson Fil learned all this time was not to put all her eggs in the same basket. However, she also learned that sometimes, she needed to take a leap of faith. Risk was inevitable and in her case, she had to make a timely decision the moment she found out Marcus was going out with Elise, and when she "encouraged" the same man to break up with Elise. 

Naturally, Marcus's attention would fall right back to her. Fil couldn't afford a person clinging to her or having these trashes find their way to pollute the relationships she now has. Hence, to end it once and for all, she had to trust Michael.
