Do you mean you liked this guy and he ended up hooking up with another girl that dressed better and wore makeup and you think that to get what you want you need to change your ways and become exactly what you hate? (Sounds like a good movie plot there)

Regardless, it's personal preference, if you like it heavy, put it on! If your subtle, be gentle with it. Its best to sit infront of a mirror for a while and test colour on your skin/lips.
Also, believe what you see, you are beautiful with or without.
