attraction would usually turn into neediness and make me obsess over a girl. I think right now I'm subconsciously afraid of feeling that gut level attraction because I fear I will become needy again, and lose control.
I used to observe myself a lot in the past (as peregrinus suggests) and you know what I figured out?
that it's not the feeling of attraction that was the problem it was my thoughts. I just used to overthink and then I saw that most of my thoughts made no sense at all...
for exmaple, I'll give some of the thoughts that went in my head in the past:
I saw a beautiful girl, felt attraction and then my head started:
-what if this is 'the one' and I say something stupid and screw it up
-wait I'll never have another chance with her again, I missed the girl of my dreams.
-oh wait a minute what if she rejects me and I'll feel so bad that I won't feel like approaching anymore girls in the future.
-What if I miss this opportunity and I'll never find another girl like this again...
After observing myself and my thoughts like this a few times I laughed and said: WTF?
I have a great imagination and my mind keeps coming up with great comedy. I see girls that I don't know and my mind already makes up stories and scenarios that are just fiction.
See what your mind is telling you while you observe
