Is it uncommon for friends to become lovers?

This is kinda a two part question I got into an argument with a female friend and I believe she is very sheltered based on what she is saying.

I told her that there are plenty of friends out there who become lovers and I don’t think it’s unreasonable to say that’s is fairly common and I also said that it’s not that big a deal if someone befriends you as a way to become closer with a friend that they are romantically untested in.

She thinks your apparently a disgusting person if you befriend someone because your untested in their friend. Basically because she thinks the friendship isn’t genuine at that point. She also paints a picture that you needed to be friends with her just to get close to said individual you’re untested in.

Personally I think this is a bit conceited and dramatic I’ve heard both men and woman doing this and I also I’m pretty sure this is fairly common thing that people do.

Especially from a guys perspective we don’t need much to be genuine friends so the reason we became friends usually matter little I can’t speak for the ladies but is this that big of a deal. I also feel like she is also partly making this a big deal if guy in particular does it

I don't know if it’s just me or if I’m outta touch but I feel like if anyone’s outta touch it’s her , like as a guy if someone becomes friends with me because they want my friend but we are actually really cool I’m tell you to shit your shot.

She has this mindset that if someone rejected you guy or girl and your still have mindset that things can change that your wasting energy and time. And you should quite on quote know your worth and go were your wanted.

And that even if things change your just someone second options bro your never anyone’s first option I don't know am I crazy or is she a bit out of touch?
