I completely agree with you. Infatuation is the correct beginning. I say this because I was completely in love/lust with three people in my life. I was attracted to them until they dissolved the relationship. At that point there was nothing I could do. I had to let them go; it was their choice. I respected them. I deeply loved them. I have tried people who are good for me, but sex is the ultimate arbiter of longevity and not being attracted to someone makes for a friendship, not a romantic partner. Infatuation with someone who is equally infatuated is what you have to wait for. I don’t believe anything else will stand the test of time because the person not in love (not infatuated) is having to fake his/her interest and lying is neither love nor lust. It is destined to fail.
