how soon is too soon

When is it ok to get together with someone who just got out of a relationship?
well here are the guidelines.
*DISCLAIMER* every situation needs its own approach and should be treated delicately. these are the absolute bare bones guidelines, and are geared toward the malesss...

Situation 1 (least complicated)

New girl you have just met for the first time and she just got out of a relationship with a guy you don't know. It's go time. You come on carefully. Read it out. if she's not interested back off entirely. if she's mixed signals, go in slowly and don't be pushy. If she's going for you, all bets off no time period just go for it.

Equation: signals + body language = answer

Situation 2 ( more complicated)

you know the girl already but don't know the guy. so this is how it works. you give yourself a rating of 1,2, or 3. a 1 is the best. she is coming on to you and all is looking ok. 2 is she shows interest but still a little hesitation. A 3 is slightly interested, occasional flirting but more of friends. And a 4 you should be reading the friend zoned article.
So after your rating, you plug it into this equation (Her previous relationship length) * (your number)/6= time until its ok to get in a relationship with her.
for example if she was in a relationship for six months, and you gave yourself a rating of 2 the equation would be (6 months)*2/6=1 month.

Equation: (Her previous relationship length) * (your number)/6= time until its ok to get in a relationship with her.

Situation 3 (most complicated)

its your homie's girl. bro code. in this case you probably should not go after her at all. Especially if it is your close friend. I do not recommend persuing her, but if you must here goes.

Get approval from your friend if you still want to be friends. not just an ok ya whatever, make sure its sincere. an approval is a 1. a non approval is 100 and a partial approval is a 2. Then you rate yourself again but this time the lowest is a 2, then it goes 3 and 4. after deciding your rating here's the equation.

|approval of homie|*(previous relationship length) * (rating)/5=time until its ok to get with her

please note these are serious equations that I have spent years researching along with my fellow colleagues at Harvard.

Best of Luck
