I’d be more inclined to believe Basic people need good friends. True…some people can’t be reached because they refuse to be open to their own weaknesses, but the vast majority of us in this world do not enjoy being miserable…or lonely…or angry.
As for the girl in which you are interested…I have no miracle advice. You need to be confident in what you want out of your interactions with her. That’s difficult to achieve in practice, but no matter what, you need to be honest with her and yourself. Do not make assumptions about what she is thinking; just focus on being in the moment. Forming a relationship, if that is what you want, starts with friendship. Plus, always remember that many people are just as nervous about letting others see their insecurity as you may be. Just by speaking about her here, you have shown the willingness to be proactive in your desire to form a closer bond. Hold onto that feeling and remember; if things do not work out or become uncomfortable, own the disappointment as much as you would success. Let go of resentment as soon as it comes, because that shit will destroy any other chances to be real with yourself or others.
So, as simple as I can say it: you cannot appreciate how she is going to react to your interest if you are worried about your own feelings of anxiousness. I don’t mean to sound preachy, but it just doesn’t work, friend. Don’t focus on the fact that she is girl and that you may wish to be closer; focus on her as a human that may share common interests with you. When you start feeling anxious (and you will) try redirecting that energy with humor. It is much more difficult to recover from cold, nervous silence than it is a heartfelt laugh.
Good luck and be the most transparent and honest version of yourself. If you go through life trying to play games with others’ emotions, you will be sorely disappointed when you ultimately discover no one is going to want to play by your rules, so it’s best to never start relationships that way.
