Hi Chopin,
I first want to say I wish I had your courage and willingness to hear honest feed back that you have in order to even post this question.
I've personally never experienced you as having poor social skills. Although I understand the feeling, as I've felt like I don't fit in/ know how to do relationships very well my whole life too.
I also didn't know you have BPD, but from what I've read on it it's a very complex condition that takes a lot of vigilance and continued support from others, as well as willingness from the person to keep working on it. I see you as someone extremely compassionate and caring who wants to help others. So congratulations on how far you've come already!
To your questions: I don't see you as attention-seeking or manipulative. I've never been offended by you. I honestly forget the other questions, but basically I think you' About leaving the forum, I think you should follow your heart on that one. There's a big area of middle between posting on here at the level that you do, and leaving altogether. You could only respond to certain people if that's an issue. You could respond to original posts without reading anything else that's been in replies which is what I'm gonna try and do. You could come on and PM people you feel you work well with, also something I'm trying. It should be up to w you and what you feel you can handle not your t's or husband's oppinion.
I really hope this helps.
