Will it be safe and helpful to share these channelings with her?

It is better for her to know the truth of things here, as it will bring, in a way, not only some understanding but due diligence needed to be aware of all the road hazards of life so she can be more on her guard and follow her heart more than her head when entering relationships. This was not her fault, it was not a shortcoming of hers. When people are manipulated, it will happen because this cannot normally be resisted. We are only saying that she has the wherewithal to guide her life if something is not imposed on her, and that is all that is needed to bring happiness because decisions she makes will be sound, all other things being equal, if she does not over-interpret this strange experience as a reason to give up on the possibility of love and to withdraw from life as a consequence. You can reassure her this is not the object lesson, but simply that she, like everyone else, is being manipulated by extraterrestrial influence one way or another, and it is better to know the truth so you can make the best of your life and enlist the help of the divine realm, and that can make all the difference in keeping you safe and allow greater happiness despite the complications brought by the interlopers.
