Ladies, I Need Your Help and Opinion

What is a man to do?

When he opens up and pours his heart out to a women, is faithful an true, and genuinely falls in love with her, when she tels him that he is special to her and is so different from other guys, and she loves him too.

He treats her as the queen of the world, writes beautiful writing and poetry all for her, never lies, and is totally honest and true to her, he does everything in his power that she asks of him (and the things that she don't have to ask for) to make her the happiest and most special woman in the world. He writes to her, hold her, hugs her, massages her, and loves her with every free moment of time he has.

However all along she was hiding secrets from him and lying, she hid the truth from him, that in the beginning she was toying with him just like every other guy before him, her stories were all lies her word and poems the same as those sent to the men before him, she was playing with him as a fool. But one day she realizes that he is real and she falls in love with him, but not after she still goes out and sees her ex's and even talks to other men on the internet. now she feels sorry and really loves him. but she is afraid of him finding out the truth so she sugar codes and lies about things so they seem better.

However he is too smart, he begins to see her lies and she even lies right to his face over and over again and each time he find the proof to the truth, and finally after over 2 months of lies (which he has stuck by her the entire time) she finally gives the real terrible truth about her past, with terrible acts and all of which cant even be mentioned here. NOW she loves him, NOW she wants to be true.

The man loves her with all his heart but his patience has run thin, does he deserve this? he doesnt want to leave her and hurt her, but he doesnt want to stay and continue to be hurt, he also does not wanna be left all alone in the end, what did he do to deserve this, what should a real man do? why do women (including her) complain that there are no real men, yet they are shocked to find one and they treat them like this? why do nice guys finish last?
