Could a man be falling for a woman when he tells her that he has missed her very much in only a few days?
It's highly possible and only time will tell. Most males that are just friendly at work don't tell the opposite sex they miss them in just a couple of days. Hopefully he's single and if so wait a month or so to see if he asks you out and if not then invite him out for dinner.
Why would a man flirt with a woman then seem to be falling for her and when she responds to him he tells her you need to find somebody like me?
Reasons that you could be missing your period are, You are a very athletic woman, there have been cases where woman will stop their periods when they physically exert themselves for long periods of time. You could be Malnurished, wether it be from anorexia or Bulimia. Then there is the Birth control, if you are on the Depo Shot you may not get your period at all and others stop your periods altogether.
You could see it in the woman's eyes. You would see love. When she tries to sit closer to you, we she kisses you more often, when she tells you that she loves you, or she tells you that your amazing. Women like sex just like men. If she loves you and isn't a hygiene freak, then you make a move for sex then.
When a man tells a woman she is intriguing it means he finds her mysterious and good for you! Keep him guessing. Men do love a more mysterious woman who doesn't tell all until a proper relationship begins. He could be attracted to your physical being and find you complex or, it could be things you say or do (not telling all) when he calls you intriguing. He wants to know more about you.
Every woman is different, some claim to know at the moment of conception!! more likely though, around the time your period is due you might start to have a few symptoms, and your missed period is also a huge clue.. about the time you have missed your period you are usually about 4 weeks pregnant. ~pawsalmighty
