Truth is men are more loyal than women, women tend to be selfish ungrateful beings.
I had similar experience in the past where I sacrificed pretty much everything for her and she left me when I hit rock bottom, then to make things worse she made fun of me.
I can't even describe the pain it causes in a mans heart and soul when women are evil.
You can't eat, you can't sleep, you lose all meaning in life that suicide becomes a logical choice just to end the suffering within.
Problem is love, even if a woman loves you as much as you love her. She lacks the loyalty in the long term, so she can forget the love very easily while men suffer simply because we give 100% of our love.
I think to avoid such suffering we men need to learn to be happy alone and if we do find the right woman to love, we should never love her 100%. We should think with our brains before thinking with our hearts.
It's sad really, but it's the truth.
Finding the right woman is the real challenge, you can look good, you can have money, you can have all the skills and charisma in the world. But none of that will help if you find the wrong woman.
The difficult part is women have a natural ability to put on a mask and hide their true nature for a very long time. You might think she has a very good heart and is a very good person, only to be shocked at the end that she is pure evil and was pretending all along.
The worst part is even after she ruins you and even though she is pure evil, you still keep on loving her like an idiot!
