It could be because 2 is my integration point that it seems so brave to me. I cannot imagine making myself that vulnerable, the way I see 2's doing it. I have a friend who is a female 2, and she and I were both VERY VERY interested in the same guy for a while. I was seeing him first, but as beautiful as he was, and inspiring and brilliant, I could not deal with his complicated issues. The amount of dedication he needed, to overcome his trust issues and other problems, made me feel like I was laying my heart out on a platter, and I was unwilling. I was "seeing him" for a while because of a strong mental and emotional connection, but I was closed off to him to a large degree; wouldn't let him "step on me" and couldn't make myself vulnerable. The 2, however, was able to put in the effort that he needed, and she was patient through all of his indecision and issues, and now, they're very very happy together. I learned a kind of patience and vulnerability from watching her that I never would have considered otherwise. At first, when I saw the way she was so open about her feelings while he rejected her for years (except for hookups), I thought she was pathetic, vulnerable, whiny, making a victim of herself, etc. Over the years I came to see that she was confident and determined and solid, and knew what she wanted and went for it; and ended up happy.
Of course, I'd have never been happy with this guy. While we were music buddies and worked amazingly together, and I trusted him completely, I want someone who stands on his own as an independent entity. So it's fair to say that for him, she was a good match, but for an independent person like me, who wants a lot of space and time to themselves, a 2 might seem overwhelming, even when healthy. But, I still found her dedication inspiring, and I do believe that now that he's pulled himself together, she is able to back off, have her own life, do her work, spend time with her friends, and pursue her interests. It's just that she was very gutsy when it came to making herself vulnerable and reaching out, in a way that I could never be. Because I found her so inspiring, and she did manage to help someone who I really care about, I have attempted to incorporate patience and vulnerability into my romantic interactions since then, but it's a lot easier for her than it is for me.
