He has succeeded in banging all my friends, what now ?

I’m engaged to a man who has dated at least six of my friends. I’ve lived abroad since I was 16 and only returned to Nigeria last year. Apparently he’s one of hottest bachelors on the Island [in Lagos] and has been around and slépt with a lot of these women.
It was after we got engaged that I started to find out about all his escapes with these ladies. Some of them even made sure to tell me about their past tryst with him…
I’m worried that the man I am about to marry has slept with a lot of my friends. I don’t know how to handle it or handle the girls. Anytime we are all together, it’s always awkward or the girls act too familiar with him. It leaves me very uncomfortable.
I am definitely going ahead with the wedding, but I just don’t know how to handle the situation.

What should I do?
