I guess I'm just not ready to commit.

I need some space.

I'm not good enough for you.

I've developed a skin condition and I have to avoid all excitement for a while so it will go away.

I went through past-life regression and in Ancient Egypt we were brother and sister. So we can't be lovers, it would be like incest.

You make me deliriously happy, but to succeed as an artist, I need to be miserable.

You love me so unconditionally that I lose my drive to be more.

You're bad for my business initiative.

My parents really like you, but I have this thing, I can't be attracted to someone my parents like.

I can't deal with someone being so nice to me; I'm not used to it, it's disorienting.

Couples start to look alike, and I couldn't stand it if I started to look like you.

I'm into the chase. Now that we've been together, there's no mystery.

I like your fantasies so much I'm switching sexual orientations.

Being with you has helped me see the light. I'm becoming a nun/monk.
