You must show her these letters, she has to know the risks. And by not showing her this, it's just as if you are hiding the risks. You, would be making a huge mistake not to let her know of this important information. If she regrets it later on, and finds out you had this information and didn't let her know, she'll never forgive you for this. Are you ready to take on such huge responsibility. It's like she's skydiving for the first time, and you are hiding from her the manual where the risks are outlined and casualty cases with details of how it happened. Not right at all to hide this from her. The risks here are much worse in intensity than a happy outcome - meaning if it works out, she'll be happy, but if it doesn't she'll be devastated for life. This is no time to play the supportive boyfriend part, it would be stupid at best. It's like she is jumping from a bridge and you don't know if she'll be hurt, but you are like, I'll support her cause that looks noble. It's not noble, it's stupid! Give me her email, I'll send it to her, she has to know the risks!
