This happened last night.  Out of nowhere we got into a discussion about a very unimportant topic, but one that had to do with me.  She said that there are things with my hygiene that affect her which I refused because I have always tried every time we are together to maintain my cleanliness as best I can. 

 Out of nowhere this issue bothered me and I asked her if she wanted to know when her hygiene problem "affected" me.  She said yes, and at that moment I let her know on one occasion where during sex, I lowered her pants and noticed that "she hadn't cleaned herself well."  On that occasion she was very ashamed and felt bad and I explained that I did not care.  

The point is that as soon as I mentioned this, she answered me with an audio crying uncontrollably where she explained that she never thought that I would throw something like this in her face and that she had never felt so humiliated.

It wasn't long before she told me that she'd rather break up with me, that she couldn't bear something like that.  I really understand it, what I did was something horrible and I am totally sorry, and worst of all, it hurts a lot.  I know her too

A month ago I was diagnosed with BPD and I have read that these things often happen to those of us with this disorder.  The issue is that now I don't know what to do, it really hurts me to have done this damage to her and I want to repair it but she probably doesn't want anything more.  What I can do?  How do I deal with this guilt?

I'm desperate.  Please, any advice you can give me I would appreciate from the heart.  Thanks for reading this
