You're not the problem my brother. Sometimes we just have to re-evaluate certain things.
One piece of advice I'll give you is this. One thing that really stood out to me while reading your pursuit of this chick was you mentioned you felt like you were walking on eggshells while trying to get to know her. If that was case with this girl, you were too concerned about impressing her & worried about being who you thought she wanted you to be, instead of just being yourself. It's fine to want to leave a good impression, but when it takes away from your true self standing out, you come off as insecure & insincere.
Sometimes all it takes is some fine tuning & a little attitude adjustment. Confidence is key, but always be yourself.
I don't think I felt like that with this particular girl. I did avoid some topics such as politics but for the most part I wasn't walking on eggshells. And I won't talk about her in the past tense yet. It's not over yet.
