This "lets me friends" thing is him wanting A

A is the easy choice, he doens't have to do anythign and he gets his ego stroked by two women at the same time...

Who would want to choose b or c when they can have a?

No one

That's why he's doing it... The "lets me friends" thing is bullchit... He's USING YOU.

Friends dont' lie and two-time each other... cut off access to YOU ASAP

Don't be mean, just shut down teh emotion bridge between you two until you are out of there
