She sounds very insecure of herself, seeking fulfillment and self-worth in the wrong people and places.
Not everybody handles being called out the same.
Some are more reasonable, some more temperamental, and some people just be cray-cray.
While I think your intentions may be for her best, and your actions as well, it seems like you found the right combination where her reaction to it isn't so good.
If your friendship means anything to you, then I would try to patch it up.
Personality issues such as seeking fulfillment through compliments and attention isn't something that goes away easily. I would think the deeper those insecurities run, the fewer people they can respond to calling them out.
Even with the right friends, her issues sound like something that she really needs to realize herself. And even then, realizing it and coming to terms with it can take years. Let along learning to fight it alone and with the support of others.
I think the questions you must ask yourself are:
- Do you think she is worth your energy?
- Do you think you have the energy for a long term friendship?
If you don't, it's ok as well, not everybody is strong enough to prop up those around them.
Just be honest with yourself, if you mean well, but can't follow through with it, then I would say just explain your intentions 1 more time and leave it at that.
Side note as a fellow Christian.
I have seen a strong intentional community with brothers and sisters change lives. Are you ready for that?
