I think what it is with me is I fear rejection. I have had a lot of rejection in my life, and now it has put me off pushing the friendship further, even if I know they like me and are willing to get to know me more. Then I suppose they can sense that I'm not keen on asking them to meet up outside of work (or wherever I met them), so they don't really ask me to come out either. Maybe they feel the same as me - they think I might refuse to, especially knowing that I'm quite a shy person, and they're afraid that they might be putting me under pressure. So both parties are as silly as each other (me and the other person). So hopefully that's the case, and not anything against me.
I've been accused of ''not letting other people have space'' before, so I think that's what's off-putting about building friendships further. I keep my distance for that reason only. I'm scared that I'm going to appear too needy, and then they're going to back off, and then I blame myself for it and wallow in self-pity. It's not so much missing body language. There is no body language to miss. A person likes me, they go out of their way to talk to me, they even trust me with their secrets, and I know that trust is one of the important signs of a friendship, so I think ''oh, this person seems interested in me, maybe it's the right time to get their number'', and if they are interested enough (which I can usually tell that they are) I get their number or add them on Facebook or something, but if they don't contact me that often I'm always afraid to contact them in case I get accused of ''interrupting their privacy''.
But friendships have got to start somewhere, and sometimes it has to take a little push to build it up, and also friendships take two. I try to sound willing and friendly and do the best I can to build up the relationship, and I don't think I do too badly either. But it's when the other person isn't making the effort, is when I immediately stop. And then we drift apart.
It's like entering a friendship is like walking very gingerly across a very weak bridge over a river. I take it nice and easy, but when I feel the bridge crack or hear a creak, I jump back again, and hesitantly try again. That's how I feel with friendships. I find you've got to tread on eggshells a little bit when first meeting people, because you've got to keep at a precise level and not go anywhere near the ''being too needy'' mark or the ''not interested enough'' mark. Most NTs seem to know how to keep that level with most friendships (not all - even NTs make mistake, but generally it is not an issue like it is for me).
