You are doing a good thing by coming here and posting. There is a lot to learn about BPD, and lot to read on this site that will be informative. Please take some time to explore. I think the best place to start is
here.
What I found was that there were steps I could take help make me feel better about what was going on in my relationship. Sharing here was one of them. I developed others along the way.
Is there one thing that you would like help with right away? something you would like to focus on ?
