Why, when I find a girl that I can actually talk to and have an in depth conversation, she always ends up "running away"?

I too, at times find it difficult to allow myself to like a guy. I can't speak for this girl, however I know that in my case, the fact that I was very much so abused by the closest men in my life, makes me run from any guy. I always thought I wanted to find my true love, however, as I've gone about this journey looking for him, I find that every guy- wonderful or not, makes me scared to "love" him. It's this panic feeling I get in my stomach the moment he says things like "I care for you...", "I love you...", "I'm falling for you..." etc. The truth of the matter is, with girls like us you have to go slower than the rewind button on your VCR. It could take weeks, months, maybe even years for us to know we can truly trust that guy. For us to know, that he really means what he says. It's absurd, I am aware. However, it's not something that can be explained entirely. It's something you learn from experience.

Well for one thing, you are blaming girls for your problems.

Your little definition of you being Casanova is cute and that is exactly why girls run away from you. You say that to give the impression that it's not your fault and that you have confidence but in reality, it's not there. People who are confident don't need to make any silly remarks regarding it.

"that this girl in particular had something happen in her past that she hasn't gotten over, therefore, I am stuck in a hard place."

- blame game.

So why do girls run away from you after these in depth convos? Well they talk to you, they sense red flags and they run away. Are they b1tches and leading you on? Are they all crazy hoes? Or did they get to know you and realize you aren't the right one for them?
