The 'how many' doesn't matter.

What matters is the experience with her. Like:

Do you really pay attention to what I'm telling you?

Do you feel that being with me is what you want?

Do you have any doubts?

I'll be able to feel these things, but I need her to say them out loud, in the most sincere way.

I want a partner-in-crime, someone who doesn't want to fight but build together, you know?

It's pretty basic stuff, but somehow it's so hard to find people like this.
