For Marriage
It is not a suitable case at all. Definitely abandon it, otherwise, you will regret it.
For Business / Deal
It is by no means in your best interest (Salah); you will fall into a pit from which escape is very difficult.
قَالَ إِنَّمَا أُوتِيتُهُ عَلَىٰ عِلْمٍ عِندِي ۚ أَوَلَمْ يَعْلَمْ أَنَّ اللَّهَ قَدْ أَهْلَكَ مِن قَبْلِهِ مِنَ الْقُرُونِ مَنْ هُوَ أَشَدُّ مِنْهُ قُوَّةً وَأَكْثَرُ جَمْعًا ۚ وَلَا يُسْأَلُ عَن ذُنُوبِهِمُ الْمُجْرِمُونَ
Qala innama ooteetuhu AAala AAilmin AAindee awalam yaAAlam anna Allaha qad ahlaka min qablihi mina alqurooni man huwa ashaddu minhu quwwatan waaktharu jamAAan wala yusalu AAan thunoobihimu almujrimoona
