You arent doing anything wrong if you lose her that is on her! I hate to say this but if she decides to do it theres nothing you can do to stop her. Sometimes losing(hopefully not to sui but just in general)what we thought was a friend turns out to be a blessing. Im not say that it wont hurt but in all honesty if you met her in a forum like this you have no real idea who she is, her history, how true anything she has said is, or anything else for that matter. I think you really need to focus on YOU! Are you in therapy? Could you talk to your therapist about this? This situation isnt healthy for either of you and I am not a pro so I can only give you my experience. It concerns me quite a bit that you are so wrapped up in the situation. Until you talk to a T feel free to keep posting and we will do our best to give you our experience or opinion.
