Weird, I was researching emotional abuse online today.
I have been in relationships like that. It's horrible. It eats away at your ability to have faith in your own judgment. I don't know how to break that. Honestly for me, it was GG and my ex-girlfriend who got me through. But I'm not really sure how. He just loved(s) me through everything-always having faith in me. She told me I was beautiful like water-then explained what that meant to her. But-how to reach your friend? Support her?
I don't know her. Remind her of what it is you see in her that is beautiful, strong, resilient, worthy as often as possible. Because these are the things we lose when treated with such abuses.
