Valid Marriage

Assalamualaykum, Dear Sheikh, I want to put forward my situation to you and want you to please advise me what I need to do according to Quran and Sunnah. Myself and a girl started out writting letters to each other about 6 years ago, Me and the girl were aware of the sins and were told to stop by our parents but did not listen. We even wrote letters to each other quoting from Quran and Sunnah that what we  doing is HARAM we should not see each other and we handed the letter to our parents but we deceived Allah and our parents. At night time I would go to her house without her or my parents knowing and she would let me in. My parents were very upset and because of all that I was doing my mother became ill. Me and the girl then got married in a car park but she had no wali present. It was just Myself, her and 2 witnesses.the car park nikah was done prior two years before I ran away, her parents found out first. Her father went to my uncle and mentioned to him my uncle said that this is not a valid nikah according to shariah. My uncle then told my father that your son has got married in the car park 2 years ago, my father rang the girls father saying what I am hearing is it true and her father said yes so my father said why didn't you come to me he said I don?t care and I accept this nikah because my daughter approves it. (At this time me and the girl also thought we were married because we were told according to Imam Abu Hanifa the nikh is valid, and she was a Hanafi). When my parents asked me is this true that you got married I denied and had always denied till I ran away. Before I ran away from home I use to visit the girl at her house, her parents use to allow me in and I use to take her out without my parents knowing.at the time we both thought that we were married. At this time her mother and father also accepted that we were married. I then ran away from home and lived with the girl for a day before returning back home. Before I returned back home my parents went to the girls house to bring me back home but the girls mother and father spoke rudely with my parents and said if you want your son back you have to go through us.. When I returned back home then we came to know that because the girl never had a wali present at the nikah the marriage was void. I then left home again and we got married with her brother present as a wali, Her father refused to be present at the second nikah because he believed the first nikah was valid, However myself, the girl and her brother believed that we needed to do it again. The girls father agrees with the first nikah till today. Before the other nikah took place I use to visit her house behind my parents back there did not know anything about it. The girls parents  allowed me in the house  and I use to take her out as well. Even after Knowing that the car park marriage was void. We were doing HARAM. My parents did not know about the second nikah until later there found out from somebody, When my parents found out all this was happening behind their back my mother rang the girls mother and said what is all this we are hearing, the girls mother said I respect my daughter and I have nothing to do with it, my mother said that this is Haram for oppressing a Muslim and not obeying Allah shariah. She replied let us make it Halal. My mother said we do not have the permission of making Haram Halal. I repented for the sins I had commited before we got married but at no point left the girl. The second nikah was done after 3 days when I ran away from home the second time, and by then I was living with the girl and was repenting but did not fulfil the conditions of tawba by leaving the act When my parents after a month tried to get through me their told me come home lets talk I said if you want me then you will have to accept her aswel, I was trying to blackmail my parents was it right not to respect and obey my parent because of what I did, because Allah says do no obey your parent when there tell you to do wrong.The Prophet  (peace  and blessings of Allaah be upon him) said: ?There is no marriage without a  wali.? Narrated by Abu Dawood, 2085;  And he  (peace and blessings of Allaah be upon him) said: ?Any woman who  gets married without the permission of her wali, her marriage is invalid, her marriage is invalid, her marriage is invalid.? Narrated and classed as  hasan by al-Tirmidhi, 1102; Abu Dawood, 2083; Ibn Maajah, 1879 ? from the  hadeeth of ?Aa?ishah.this is the principle that was followed by the companions of  the Prophet  (peace and blessings of Allaah be upon him), including  ?Umar ibn al-Khattaab, ?Ali ibn Abi Taalib, ?Abd-Allaah ibn ?Abbaas, Abu  Hurayrah and others. Thus it was narrated that some of the fuqaha? of the  Taabi?een such as Sa?eed ibn al-Musayyib, al-Hasan al-Basri, Shurayh,  Ibraaheem al-Nakha?i, ?Umar ibn ?Abd al-?Azeez and others said: There is no  marriage except with a wali. This is also the view of Sufyaan al-Thawri,  ?Abd-Allaah ibn al-Mubaarak, Maalik, al-Shaafa?i, Ahmad and Ishaaq. MY PARENTS ADVICEthey always told me that this girl was not good to me for my Deen because of her character, and we will not help each other in Birr and Taqwa. And after experiencing the girls parents behaviour regarding the Deen my parents said even they are not good people. (My parents are not accepting this because their say I am living in sin and they don?t want to get involve in the sin their will do sabar and please Allah by obeying his commands) My parent are telling me I did not fulfill the condition of tawba by leaving the act and  I am still in the sin. Since then I have not been home for three years, I do not get on very well with my inlaws because of the way they treated my parents, however me and my wife are happy together we also have a 2 year old daughter now, And Alhamdulillah  we have been and still are practicing islam. The only thing missing is my parents though, I have put forward everything to you would you please advise me from quran and sunnah what I should do. Do I carry on living with my wife? or do I divorce her and go back with my parents?and also If at the time of the second nikah the girl still agreed with the first nikah then will the second nikah still be valid? Jazakallah Wasalaam,
