Sita A different perspective

People always praise Lord Ram. I too grew up on a house where Ram played an important role among our family members.

My grand father a great devotee of Lord Ram used to chant his name always. That had a very positive impact among all of us. We too subconsciously praise Lord Ram. 

As days passed by I read about the story of Lord Ram. A very good student of Guru Dronacharya. He had learnt lots of techniques of Arrow and Bow. Dronacharya took him for swayambar 9f Princess Sits where he broke the shivadhanush. Which made everyone surprise and made Ram a good warrior.After returning home when he was about to crowned by his Father as the king of Ayodhya a dirty conspiracy came and he was asked by his father and mother kaikayi to go to forest on exile for 14vyears.Hearing this his wife Sita and younger brother decided to go to forest with him. Finally all three went to forest. Losing the son his father passed away. All the three had to struggle hard to survive at the forest. They lived a very simple life.

Then one day Sits was attracted by golden deer which she told ram to get for her. By dirty game of Ravan Maricha had disguised into a golden deer. When Ram caught hold of him he came to his own form and shouted calling help for Pacman. Hearing this Laxman was not so keen to leave sits alone in the forest he drew three lines and advised sits not to cross the lines in any case and ran to forest. By the time he reached near Ram seeing Marcha both understood the game plan and ran towards the future where sita was there. There was nobody someone tricked them and took sits they got convinced. Then they started searching for her. On the way they met Jatayu a big bird who told them that Sita was taken by Ravan the king of Lanka in puspak bimana. Hearing this they ran and met hanuman, Bali made friends and with the help of the Banaras they made a passage in the sea. 

Raven who had kidnapped Sita kept her in Ashok vatika and everyday would come and ask if she has made up her mind to get married to him. Every time she refused and wanted him that Ram will definitely find her out and will come and resuce her. Raven simply laughed. Finally Ram reached Lanka and killed Ravana. He asked sita to walk in the fire to proof about her insane. 

She did that. Then all went to Ayod hya Ram became the king of Ayodhya and Sits the Queen. There few people spoke about sits being pure Without her knowledge he asked laxman to take sita and leave at Balmiki Ashram. Sits was pregnant she was totally upset when left by laxman. She gave birth to twins Laba and kusa. Made them good warriors who at young age caught hold of the horse of. Aswamedha yagya it became difficult for all the great warriors of Ayodhya to defeat the twins. Finally King Ram had to come and fought with them he was also tied then he came to know that these two were his sons. He then took them to his palace before that asked sita to walk in the fire to prove her purity. This time Sits was so disgusted that asked mother earth to open and embrace her. 

Sita what mistake she had done when she did not get influenced by Ravan's word and stayed strong not got married to him.

She had given Agni porikhya but was thrown out of kingdom when she was pregnant and wanted utmost care. 

When she and her son's met Ram again why she was asked to given agni porikshya once more.

Why a lady in this mythological story was truthful but had become the victim of the society why? Is there any answer to this?
