What a pity, that girl must be suffering a lot. Loosing her virginity in such a cruel way and almost loosing the man she loves

I'm am really shocked, i can't imaging myself in such a situation, it is painful.
The truth is that my reaction in this forum may not be true, since emotion is a major factor here, but i know that i will hurt those bloody motherfuckers rapists and castrate them if possible.
Rape is not an acceptable behaviour.
Poster, i think you owe the girl two majors things. One is to help her overcome the trauma by showing her love, do not tell her you won't marry her (if that is your intention), show her all the love you can, if after she has overcome her trauma and you decide to tell her that you won't marry her based on the present situation, she will be in a position then understand you without a serious negative impact on her.
Secondly, get her opinion first on the issue of the baby, DO NOT force her into abortion (which she might opt for given how the baby came about).
