Never waste time and break your heart uselessly like that man. Tell her straight away what you want, if she's interested (which is basically 100% dependant on your looks), it'll be obvious and she'll make it RIDICULOUSLY easier for you. If she rejects you, block her forever and move on.
Less time waste, less pain, less bullshit, less giving attention to foids who won't put out to you.
Also, the uglier you are, the most machine-gun-like you have to be about that. Focusing on a particular foid and trying to be friends first, etc, is a poor strategy even for Chad and an ATROCIOUSLY BAD one for sub5 men.
