I haven't researched a lot yet and only know bits and pieces about pbd, so maybe keep that in mind. 

So it's been a few days since my ex, who has bpd, broke things off after 4 months. He says things have been pretty bad lately but he thinks he can manage to stay friends. We've been friends for years before we started dating so I was glad he wanted to stay in my life as friends at least. I haven't heard a lot from him and want to know about his well being but he said that I shouldn't check up on him so it's probably the best if I give him time to deal with what he's going through. I want to be understanding and I'm trying really hard but still, I miss talking to him and wonder how long this will go on because I'm worried about him.
