I'm afraid...

I’m afraid that you’ll fall for someone else.

I'm afraid some one might take you away, 

I’m afraid you’ll lose feelings for me.

I’m afraid I’m not good enough for you.

I’m afraid that you won’t feel the same way no more.

I’m afraid that you’ll leave me out of no where.

 I'm afraid some one will make you happier and leave

I'm afraid of losing you and not staying beside me, 

I’m afraid to just not have you in my life anymore.
