Unfortunately I did not handle my last relationship well, and she ended up breaking up with me. But for future use if I ever get back with her or if I date anyone else with BPD. What can I do to show I love and support them and am there for them. She would go from very hot to very cold. And I wasn't able to adjust or help.  She would have screaming fits, and a few other things. So I guess what are some dating tips, to date someone who has BPD.
