Is she obsessed with me? Can 2 narcissist fall in love with each other?

My ex is obsessed with me. Last day I went out with her to smoke since she refused to come to my place. Initially she refused, but later allowed me to touch. More like the way I want. She asked me why I didn't kiss and I purposefully didn't do it. But I saw in her eyes, there was no spark. Like she was bored of me yet wanted my company. So I asked her if she is obsessed and she declined. She dropped me at a supermarket and followed me in, in the pretext of buying and on silent ally called me a narc and cruel.

But she says she isn't obsessed. She once saw me at movies and was sitting next to me but didn't talk or even make an eye contact. When I asked her she denied going to movies. I tried to touch and she refused, eventually agreed. If she ask for nudes and I dont respond, she blocks me then unblocks. Her texts are often around night.

If I brag about my life or size, she just doesn't even respond. Yet she somehow is obsessed with me.

Now at work, she doesn't look at me or talk to me or even smile. Not that she badmouth, but seems to not care.

Is she obsessed with me? Can 2 narcissist fall in love with each other?
