I'm afraid that one day, you'll get
bored of me. That I won't be as attractive to you, my personality
won't be as interesting, flirting with me won't be as fun,
spending time with me won't be as special, you'll have less to
say when we talk, you won't touch me like you want me. There
won't be anything new about me that will surprise you, & then
you'll start to look for someone to replace me.
