How can I make the balance between my best friend and lover?

It is a difficult task to make a balance between my best friend and lover. Both of them want my devoted time. After a few days of tantrums from my girlfriend and taunts from my best friend, I have come up with a master plan to balance between them.

Whenever I make plans with my best friend, I will tell my lover that I have an exam and is doing combined studies with my classmates and please do not call or disturb me when I am with them, as they will make fun of me.

And when I have any movie plans with my lover, I will tell my best friend that I am going out with my mom and dad, so please do not call me.

I know it is wrong, but with this lying, I am saving my skin.

Till now this is working out well ... let us see ...
