Hi ann6835,

I feel awful because I miss this person that was such a part of my life and that I had grown to love and also because I really feel that they need help and that my leaving them is leaving them when they need someone the most.
Probably all of us here felt awful days after the breakup, it's normal. I think that many of us can relate feeling guilt about our pwBPD. My ex survived long before I met her and she'll survive long after we divorced. The love that I had for her at one point is not above the disorder, it also can't cure the disorder. She has to be motivated and want better mental health for herself.
I believe in my situation and it doesn't necessarily mean that yours is similar, it may be similar for someone else, she has a lot people that are enablers in her life. I was her fixer and helper too, she depends on others for things that she should be doing herself. I removed myself from the group of enablers that surrounds, one less person may mean that she'll get help sooner rather than later.
I notice you don't talk about yourself much, your talking about her mostly. You might want shift that focus away from her and focus on you and your needs.
I]first night there I asked her to stay off of facebook and enjoy the city with me and she exploded, it got so intense that she smashed her head against a wall causing a huge cut amd a lot of bleeding. She needed medical treatment but refused when security showed up
I read lack of impulse control and rigid thinking l, but she may also have adrenalin going through because her head hit the wall and she bled. It sounds like it could a mental illness of some sort. We can't diagnose, only a professional can do that! What we can look at are traits of BPD and we can set boundaries on those traits, boundaries are like an invisible outward layer that protects from bad stuff and it keeps the good stuff in.
Regardless of what mental illness that she has, I think that you could set some boundaries, death threats should taken VERY seriously.
