I think this says more about you than her. I am really old fashioned, I think her texts are Her business to share or not (like a letter, a land line call, a journal)---
And, frankly, it sounds as though you read a lot into what is shared with you.
You can have friends, and business relationships, with people of both genders, any sexual orientation etc., the fact that you cut yourself off tells me that you don't trust yourself. And, how could you, then, trust another...
