I just discovered she had captured a private message between my mother and I regarding her and her illness. We were discussing what her father and I talked about and there wasn't much too much information in it, but I was a bit flabbergasted she had caught it I was being careful... . No I could delete it from her computer but there was nothing too harmful in it. I don't know this little piece of information seemed shocking anyway. I guess the craziness is she is she didn't bring it up to me only emailed herself regarding it.
Ah, computer games! Can I play, too? I'm already there... .
Seriously, though, if you did not trigger a bad reaction from her, then... .you didn't. It is kind of a consensus around here, however, that telling the BPD in our life that they have it is not a good idea. Of course, loving them, and wanting what we think is best for them, it is hard not to. I threw it out at mine two months ago and it scared the heck out of her. That was before I ran into some threads here saying that this was not wise (and all but useless anyway).
Does she actually know she has BPD or as been diagnosed? What about any other mental illnesses? Are you or she in counseling together or separately?
Mine was diagnosed a few years ago with depression, but her therapist isn't making the connection that it is co-morbid with something else (the BPD, in my opinion). My X and I are all but done, though still living in the same house for now. She does, however, exhibit this behavior of writing things to herself on the computer. Occasionally, I have found them. Others, I hit upon by accident when doing a ctl+v (paste) and I found some things that were quite shocking to me, though they did enlighten me further about what's going on inside of her.
I found a note the other day and I responded to it (left it up on the computer). Two days later she saw it and said that she didn't mean for me to read that. I replied, "consciously... ." She just stared at me. Interestingly, two days later, I found this new journal she was writing in, and she left it out in the living room. I noted an entry; snapped a photo to document it. The next day, she left it on the table on top of some of my stuff. More entries to "herself." Weird, but again, enlightening.
All in all, if you are at the paranoid stage I am at (well, I am past that, but now still trying to make sense of this twisted world), if you use the same account, cover your tracks. Selectively erase your browsing history. Don't ctl+v,c text that you write.
