Help needed Pls. Marriage on verge of divorce due to infidelity

Hello All.
I was married to my wife on March 17th 2013 and bought her to USA shortly.
Since then we are having problems and fights due to her picking fights for almost everything. She initiated fights for everything with me and my family. She would get angry even if i talk to my family. We were separated for 1 year from November 2014 to August 2015 where she left to India due to fight and got into illegal affair with a guy in India. I was in USA. Then she came back to USA in July 2016 to live with me after convincing.I did not know about her affair that time.
That time she continued affair with that guy after coming to USA to live with me and I found out with proof she has illegal affair .she continued cheating on me even after my warning. All of this cheating was accepted by her.
She left to India on March 2017 in hopes of trying with the guy she cheated on but i am not sure what is happening and till now we are separated and did not come back to me and we didn't talk about divorce too even though we have frequent quarrels over phone. She is in India now.

It would be really helpful to get inputs as i feel hopeless and confused on the next steps to do.

My Question - I wanted to know if I will get divorce .I am feeling scared or weak on initiating a divorce . I am not sure why . Will i get strength to give divorce soon or will i get divorce from my wife or Will i be reunited with wife.. I wanted to know if divorce is present in my chart or in wife chart and .. if so when will we initiate divorce? if i get divorce, is there 2nd marriage for me and child yoga.

That sounds like a terrible person. Honey, she is a menace.

You lack confidence to initiate divorce because of sun+ketu. She has the confidence to carry on extra marital affair due to your mars+rahu.
You will waste time by not divorcing her.
2nd marriage also not satisfactory

Major-period period of Saturn is operating since 6/August/2015. Saturn is in the eleventh house in Virgo and exchanges signs with Mercury which rules the eighth house. Therefore unhappiness and humiliation will be round the corner in this major-period.
Saturn is in opposition to Venus in the fifth house. Therefore Saturn will cause unhappiness relating to marriage.
Saturn is in Uttar Phalguni nakshatra of the Sun. This nakshatra has the tendency to help and generously extend relief. Its deity Aryaman stands for close friend. It represents close relationships and therefore if a naturally malefic planet occupies this nakshatra it would be an indication that there will be break and setback in such relationships. Therefore during this major-period break in marriage is likely.
For more than one year Saturn will remain in Sagittarius in transit. From here it is making very close relationship with natal Sun which is the planet governing your home life and profession. Therefore break in marriage and major changes in professional career are indicated in the next one to one and a half years.
The sooner you decide to initiate proceedings for divorce the better it would be for both the parties.
