Desperacy indeed is pathetic

I fail to understand why guys think that just because a girl is friendly with a nice face and pretty smile that they will just magically fall in love with them the moment they get to know her. How is it that they think that one nice moment or maybe a couple is enough to base anything like LOVE on? This is not a movie we are living it is real life. So be realistic. WE are all human with very real faults. Not every personality matches or even can get along well together. Is it the desperate lonely feeling they get when they haven't had a good girlfriend in a while? I think it is almost insulting a guy thinks they can fall in love so easily, meaning no matter what they say it can never be certain to you or anyone else that they won't fall out of love just as quickly. I mean hello, what will they do the first time you get mad or aggravated to them? I am the type to argue when I get bored and walk away satisfied with a nice witty argument or debate. If a guy can't do that or backs down or gets upset about it is just pathetic to me. Guys these days think that every girl they fancy themselves attracted to should be easy to get. Why should we be easy to win over? what is wrong with having standards and not giving in or settling for less than you need or deserve if you're standards are realistic. I just do not understand how they think love is so cheap and easy.
