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. 

 I used to wonder if I could ever find the right woman.

Wondering about it too much stopped me from being the right man for the best women I've found.

The more faith you can have that she's out there, the better it will be when you find her. 

 Yeah she's out there, I know that
I know it because I feel this way 
Someone must feel the same :D 

 That's the spirit
