Following familial acting patterns

I am a little bit low right now.

My worst nightmare had been confirmed. My wife is bluntly cheating on me.

I am currently on a plan to take action about it. Putting everything in order to get into one of the worst experiences someone can have. A divorce.

Her affair had been confirmed to be emotional and sexual. So my plan has been set. The reason why i make this thread is not her affair. I had already decided what i will do. The motif is quite different.

I am intrigued for how we humans tend to repeat our familial paterns. Sometimes to some people that is inevitable. I am currently taking this vertiginous train of thought. I will explain further.

I come from a broken family i was a teenager. My father simply leave the house because of his affair. He decided to live with his lover and leaved my mother to fend herself with 3 kids. I had high grades and managed to obtain very good scholarships to complete my college education. I ended up a mess, i suffer a lot beside my family. I promised myself to seek happiness with a woman to whom i will be forever hers. And do whatever i could from my part to make things work. At almost 6 years of marriage i have not cheated even once not even as a joke. I am the first doctor of my family, i had surpassed the income my parents ever had and i have the best social stability of both my mother´s and father´s family.

My wife came from a troubled family. His father was a patriarch, macho, misoginstic, uneducated, ignorant, and authoritative man. He ruled his home with iron hand. And cheated on her wife for 8 years. My mother in law never leaved him, just to be separated by his death. When i knew the story and married her i belived that she was my equal, that she decided to grow to something different. I am the opposite to everything his father was. Even phisically. And then i found out she is cheating with a man similar to his father.

VERY IMPORTANT. I am attempting to begin an opinion, and personal experience debte.

I am not interested in psychological theories (no Aedipus complex crap), or anthrolopogic studies, or relation between genes and behavior. I had already read all that stuff trying to understand my wife. I am interested in the humanistic aspect. Your feelings and experiences.

Thanks to all those who had recieved me in this site. I am very happy to be your partner. I will appreciate any story that can help me UNDERSTAND.
