Good question Paa Jee 
If you’ll compare men and women both at once you’ll find out that women feel more insecure when it comes to deciding about a life partner. Now the question is why is that?
There are many reasons for that:
1- Women are more emotional as compared to men yet more emotionally confused as well.
2- Women like to indulge themselves with someone who has/had their attention and see where that goes even though they already know someone else or talking to someone else at that given time.
3- Every woman has a trigger point that most of them don’t realize until one of the guys hit that. That trigger point can be money, bad past relationship, word of mouth of other women about men in general, amount of romance/love/fun or closeness she feels talking to each of the guys in her options individually and other similar kind of things.
4- Women who are mature or had a bad past relationship one side of them always hate men in general even though the guy they are talking to at the moment is totally opposite to their ex. They try to make a strong standing with this new guy. They like to argue more with him because they start to think same about all the men at this point and feel more insecure about everything.
5- Women who consider themselves mature in this matter are mostly the women who were being played by someone in the past. These woman also play a big role in their friend’s decision making.
6- Women don’t fall in love most of the time, it’s the guy who makes them fall in love with him.
7- Even though some girls have mentioned Sharukh Khan and Salman Khan here as their ideal men many out of them would have a lot of questions if any one of those men would come to them and ask them to marry right now. This shows one very interesting emotional insecurity about women that even though they’ve the perfect man besides them they need other women’s opinion/stamp of approval to make it perfect.
8- Women like to discuss the guy they’re seeing/talking to with their girlfriends and the guy a woman chooses at the end of the day most of the time is the end product of 2-6 woman’s combined decision. Which shows they lack in decision making as compared to men in this regard.
9- Women continuously test the guy and interrupt him whenever they can to see the response in a particular situation. Because when a woman likes someone she’s almost gone emotionally but she tries to be mature and put forward some annoying questions to put the guy into extreme.
10- When a woman likes a guy the biggest insecurity she feels about the relationship can vary but most of the time it’s the insecurity of the guy leaving her.
11- When you find a woman talking less and listening to you more means she’s taking deep interest in you and is in the phase where she can actually fall in love with you. But that doesn’t mean she’ll because at the same time if the guy isn’t mature enough to see that would start complaining and that would eventually make the woman take a step back.
12- Women like to listen to nice, decent, positive and opinionated stuff only when they’ve started to feel something about the guy otherwise they’ll put you in a totally different handbag they carry and that handbag usually contains their options and type of the guys they don’t mind but don’t really find interesting. Which means women like to feel alive before they move to the serious phase of relationship with a guy.
13- Most of the women who had a bad past relationship don’t like to go into romantic stuff easily and those type of women are most difficult to convince because once a woman has a bad relationship she becomes a totally different breed of women.
14- Most of the men don’t realize the fact that in the relationship phase it’s all about her and even after getting married but once married the woman actually embraces that and gives the man the attention he needs but before marriage it’s all about her and when guys don’t comprehend that completely they do stupid things which make the woman fed up and eventually avoid the guy.
15- Women who fall in love and get married with the guy they talked to for the first time are a totally different kind of women. They’re more positive about men and consider themselves more confident and emotionally stable.
I can actually keep going but I gotta do some stuff but I hope this would help you understand few things about the most amazing thing in the world “WOMEN”.
And try to be someone’s first and last that’s the best scenario, all the best!
