Hey doc, my friend moved away for college then started dating a girl who is the spitting image of his mom... Same body type, hair color, hair style, eyes, it's bad... Should I say something?
Ah, this sounds like a serious case indeed. You see, your friend's mom was the first female figure in his life. Now, granted that she was good to him it made him associate this figure with a very positive image that may have had an impact on his psychosexual development.
Now, moving away from one's home is indeed an act of cutting oneself from one's past; much like the umbilical cord that originally makes a child and their mother share the same body. Deliberately doing so is a difficult experience, and one that may be motivated by guilt; your friend is trying to escape his own past.
By developing such an intimate relationship with an individual so closely resembling his mother, your friend shows that he wishes to come back to a state before such a violent separation into two bodies; and he may be having sex with her in an attempt to do so. However, he cannot go back to unity with his mother because of a physical impossibility and his own desire to run away.
I will suggest that your friend, more than trying to fuck his mother, is moved by a confusing desire to become her; thus returning to a familiar state of positive unity, not with her but with himself. Well, herself. You should tell your friend to start taking estrogen.
