What Do I Do?—I Had Sex With My Girlfriend’s Bestfriend, Now She’s Pregnant And Doesn’t Want An Abortion

A confused fan sent this in last night asking for help.
Apparently, he has been having sex with her for about two months.
So we’re asking you to help this brother in the Lord.
According to him:-

His girlfriend is schooling very far away from his present location and everytime he tries to bring her over, she complains of transport fare.
He send it to her but she uses it for something else. Everytime!
Her bestfriend on the other hand schools in his own school here in Lagos State.
They see each other one way or the other everyday.
We all know kongi is strong. But according to him, they knacked just once since they’ve been seeing each other.
That’s why it is more complicated.
Now the best friend is pregnant, she doesn’t want an abortion, and he doesn’t know what to do.
