'busy' again

Whenever I text you, you will say you are busying. BTW you will also put =( and say miss me.
Which is real?

Actually,
In my deep heart, I know the answer.
I feel hard waiting for your msg.

I shouldn't have wishful thinking.

You and her,
Long distance love perhaps,
still,
having 3 years of relationship.

I think,
Both of you can go longer, right?
No body knows the answer,
God, you know?

Then who am I?
