Seeking divorce now.

Me and my wife got married on 28 april 2017 and immediately after marriage we had conflicts. She started complaining about me and not giving her physical satisfaction and I am not like other men who is crazy for sex all time. She infact tortured me saying her friends husband satisfy their wife like this like that. She was not at all happy. I work in 24*7 working in MNC. Within 4 months of marriage, she went to her parents house. and in 1 month i got to know from her that she is pregnant (she did not want kid for 2 years). I was really confused and shocked but I thought to myself that its god will and we should be thinking of the child now so i started to bend down myself. I agreed to her condition that she wanted delivery at her mom place. So i was frequently visiting her house to check how she is doing and all. wthin 1 month of pregnancy my father gets a call from her mom saying wife is having bleeding issue and doc suggested bed rest. wife never informed about this to me. i got this news from dad for which i did not react and dad told them to show to a good doc and things will be fine. Things were good and baby boy was born april 1 2018. I was told the whole time during pregnancy baby is doing fine however after birth baby was diagnosed with health issue of swelling in kidney due to which baby was having difficulty urinating. I was so down and worried about the baby. She was in her parents house for 1.5 years from pregnancy time. i was visiting in between to check on baby and her. I paid all the expense for her delivery (which was my responsibility). after baby was born he needed medical attention asap. i convinced her to come back and she came and i put all my time effort to consult different docs. finally the baby had to go thru a small cutless operation post which baby showed improvement and was now doing fine. He started to show lot of improvements and now is perfectly fine just like any other normal kid. the time when wife stayed with me with baby and opertion was 4 months. post which she called her parents and they stayed with us. now suddenly wife said one day she wants to go back with her parents as she needs to collect her experience letter from her last company. I said ok thinking she is thinking of finding a job and all. In this 4 months of stay we hardly had any sex. i was worried if i get second kid and with 24*7 job profile and baby condition i was not at all thinking of sex. havent seen son since 2 years she left. when she was at her parents i started getting below allegations- 1. i have a affair 2. I am not a good father 3. i am homosexual 4. dowry allegations 4.mental torture 6. i should go to doc and prove my sexuality and do tests etc I am depressed worried and now i don't feel to stay in this relationship.
