Thank you both.

I'm afraid that SOME small part of me, with an ego, does "like the idea of someone not wanting to live without me." I don't WANT that to be true, but I'm terrified it might be. What if some inner narcissist inside me doesn't love my boyfriend, and wants the daydream to come true, or would want it to come true if we broke up.

Again, I don't WANT any of this to be true. I love my boyfriend. But I'm terrified of the possibility that it is true, at least for a tiny part of me.
