(Fatwa: 845/000/M=1432)
If you did not give any talaq and no khula took place, then your nikah is intact as usual. Whatever sin you committed you should do tauba from it and make your wife understand with wisdom and politeness that she should continue her relationship with you and it is forbidden in Shariah to break the relationship of marriage. As per Shariah, there is no need to take permission from your first wife, but equality between two wives is wajib. It is very difficult to maintain it. Also, already thirty years have passed at first marriage; so in this age you should regain your relationship with your first wife and live your rest of life with her instead of having a second marriage.
