This short story covers the subject of abortion in which the man is trying to convince the girl to get one. To me the story is mostly about emotional manipulation. 
The man is smooth talking the girl, saying the “operation” isn’t a big deal and it will make them happy again: basically, he states that such an abortion will erase the worry that is now preventing him from projecting his love for her. This thought is probably the main reason why the girl is even considering an abortion, hence said emotional manipulation.
