Before I put in my two cents, I acknowledge that I am not aware of the whole situation and circumstances.
Okay, your #1 issue right now is you. You like this girl, but why have you formed such insanely strong attachement to her? You have to ask yourself that. I would recommend seeing a psychiatrist about this. I also used to have a problem with attaching myself to other people. My "first love" and I dated for a mere 2 months, and I pined over him for 2 years. Upon seeing the psychiatrist, I discovered that I was unwilling to let go because of the emotionally abusive relationship I had with my mother. My mom is bipolar and she swings back and forth between love and anger. Subconciously, I was seeking out relationships with controlling people. I became so attached to this one guy, that I was physically sick. I had migraines, stomach aches, dizziness, fatigue. The psychiatrist also informed me that I had severe manic depression and a touch of OCD. I got pills, counceling, and now I'm perfectly normal (depending on who you ask ). Anyway, the whole point of the story is that you have an underlying issue. A personality disorder, depression, distorted self-image, etc. This is an illness, and can be treated with counceling and medication.
Issue #2. This girl is bad for you, whether she's trying to be or not. I would definitely suggest ceasing contact with her. By talking to her, you are only strengthening your attachment to this girl. It's not healthy. It will be hard, especially with the internet around, but I think it would be good for you to stop talking to her. You've not only put her on a pedestal in your mind, you've put her on a damn altar.
Issue #3. Going to a titty bar, strip club, or whatever is not going to help you. My friends suggested getting with other guys when I was obssessing over Bob (we'll call him Bob). I ended up doing stuff I didn't really want to do with guys I didn't know or even like. My attachment to Bob only increased, and I started hating myself for being who I was. Looking at porn is completely normal, especially for the male sex. If you are obssessed with porn and retreat into it when you feel bad (which it sounds like you aren't doing), then that isn't really healthy. It sounds to me like you made a joking off-handed remark and this girl freaked out, for what reason I do not know. I probably would've laughed.
All in all, I think this is a one-way relationship and it's all coming from you. I don't think she's interested in you that way. You probably analyze every word she says to you to see if it has some double or underlying meaning. I did the same thing. When she says something, she means it and isn't trying to communicate something else to you.
The best advice I can give you is to see a psychiatrist. It's not bad at all. The first session they just ask you all these questions about you. How you feel, what you think, how you perceive things. It's actually nice to have someone just listen and not tell you what to do or think. Seek some help okay?
I hope this helped a little and best of luck to you!
