>>17 The question is "how old are they"?
Although assumed by
>>14 that they already had sexual experience in former relationships we have no proof of this yet, have we? There is still the possibility left that we´re talking about pubescent - I don´t want to call them children... let´s say - teenagers.
Have you any clue what goes on in the mind of a thirteen or fourteen year old boy/girl? Relationships in this age are still kind of playing around. There are moments when a boy doesn´t get when his girlfriend truly means "no" or when she´s just joking around wanting herself to be hard to get. Perhaps he thinks it´s a test and in case he really stops, it would seem as if he lost his interest and wouldn´t struggle to get her, you know what I´m talking about?
Because of that I suggested in
>>2 she should tell him once more, but not right at the moment he does something uncomfortable. The best option would be to go to a public place, sit down somewhere and talk to him in a serious way. He might understand better afterwards.
Just in case we´re not talking about the age of puberty, I would agree with all of you that it would be the best for her to cut the ties. But unless we don´t really know we shouldn´t make hasty conclusions and give inappropriate advices.
