FDS is great in giving you the baseline standards a man should meet. One of those is "a man paying for dinner". It's spouted over and over again.

Men can plan several amazing dates, pay astronomical amounts of money for your food and drinks, seem genuinely engaged in conversation face to face and via text ...but STILL be low value.

Be wary of men who don't invest in you in a way that doesn't also benefit him. What do I mean? He should be helping you out in hard times, going out of his way to help you especially when it inconveniences him. Some men will blow hot air and say how they would love to help you but add relevant excuse here. Whatever the excuse, it's still an excuse for him not to prioritize YOU when you need it most.

Or men won't introduce you to friends, heck even talk about you to friends ESP early on. By 2-3wks a man should have bragged to his friends about the woman he is dating.

Some men will only engage in activities that are the bare minimum. A few expensive dates? Check. Cooking her dinner? Check. A 15min phone call to "show concern" when she says she had a bad day (instead of making real effort to be present, be there, help out)? Check. Any man can do that knowing he is winning you over falsely until you drop your knickers for him.

Evaluate wisely and don't be easily impressed.
