He needs your advice!!!

This morning, I heard a knock on my door and it was my friend chuks. He had been self employed for some time now, no thanks to the economic condition of the country. He used to work in one of the banks until he was told his service was no longer needed in the unit he worked and was drafted to another unit. To cut the long story short, he was given an unimaginable target to meet at the marketing department. He got booted when he couldn’t deliver.
He ventured into his personal business and for those who think going personal is easy, they need to ask my friend. For 3 years now, he has been living like a ghost, unable to pay his usual bills forcing him to live a low life, he doesn’t even hang out with the boys any longer.
This morning, he came to my apartment because he needed advice, he told me he ran into an old friend yesterday, she proposed marriage to him and promised to give him N5million naira to revive his business. The problem now is that this same girl used to be a pass around in the office, everyone among the boys could give a vivid and accurate description of how she looked undressed! Everybody had tasted her and discussed it in the guys cycle! Now, she is offering him a life time package enriched with N5m, though he needs the money, he said he can’t imagine himself living the rest of his life with someone everyone has passed around in the office and most of them will probably be at the wedding since they still get in touch.
What should he do???
As for me? I have no advice for him. Please advice him because he is reading this page. Thanks so much.
