More trouble

Me and Coco had a falling out once again. Nothing to major on my behalf but I believe because its the time of the month for her shes a bit queasy but I don't want that to be a reason of why this happened.
After class we were walking to some place to get her film developed. I had my lighter in my hand because I was thinking of smoking or not. Coco has asthma so I was contemplating while were walking. As we walked I lit the lighter in her face, she jumped back terrified as people should. I did it a few more times from what I recall even though she was ranting on about how stupid it was. Yes it was stupid. I know, but I do it to all my friends and they get over it. I told her I was joking and I'm sorry but she was acting weird. I didn't like it. She wouldn't walk next to me, would walk behind me, would look at me weird in case I would do it again after stating that I wouldn't do it again. I'm not stupid enough to do things if people were terrified about it. It was stupid I was playing around but she just had to keep up that 'so mature' attitude and said 'you could have burnt me'  'yea great joke maaan' and was being all sarcastic about it. I was getting annoyed with it. So instead on continuing on with her I said I'll speak to you soon and I walked off. She then calls me but I didn't hear it. Then messages me a massive text saying that I need to grow up. It was an attack message. Now I walked off because I felt awkward of the whole situation. If she was going to be like that the whole time then why would I want to stay? I don't get the logic of her going all mental at me and bringing up the recent past after she lied to my face saying she was over it. I messaged her back saying I expected her to be all grown up and get over it and move on. I stopped I said I was and I did and I also apologized. I'm an apologetic person. But today I couldn't be bothered with any of her crap. My dogs sick, I'm worried about him I have other problems of my own and again she keeps expected me to be all happy chappy and saying that I'm always one way then the other way with her. The world does not revolve around you I'm sorry Coco but you need to understand that if I'm not happy with someone and is effective me a lot like my dog being sick then I'm not just going to put on a pretty face for you. I try but most of the time it doesn't work. Don't you get it, my dogs sick, my dog of 13 years might die any day soon and I'm here trying to suffice your needs. I understand that you're going through a tough time as well but that doesn't give you the right to just attack me like that for just walking away. Yes I know what I did was wrong, yes I apologized, whats the problem. Am I over it, yes. Are you , no. Theres the problem. Then we have some massive falling out over the phone. She calls me again after I tried calling her several times while I was waiting for my train. Then shit got worse and I honestly don't know what the hell I was saying but she brought up a whole new level of 'annoyingness' to the table. Bringing up all that changing the moods, acting different every day, do I have a problem with her. Well yes I do. That whole ordeal that me and the other guy (I'll name him Greg because I forgot his alias name) went through and you said you had an idea about it but played a long but again made it seem like we were the terrible bad guys. Get over it. You had two guys wanting you, and we decided to turn it into a game of who could get you first. Would you be flattered? Not like we did anything stupid like try and rape the girl, how stupid is that. Whole new level of exaggeration.
So again facebook gets involved and she posts it up on that "Some people just don't understand" and a 'friend' from class commented on it. They'v e been close ever since that recent past 'incident'. While we were on the phone she said that something happened to her while she was a kid that involved fire. Now I understand where the 'guilt' feeling is coming from. I lit a lighter in her face and she got scared. I shouldn't have walked off but I didn't want to deal with her crap. She was poking me all day and I didn't say anything and left it. She was writing to me on a blank sheet of paper while I was trying to do my work, she was interrupting me while I was trying to inbox a friend on facebook by pressing the send button with all gibberish on it. I was getting sick of it but it was getting to the end of the day so I said just deal with it. Till all this shit happened.
She called Greg  Explaining it to him and bringing up the past where he explained his side of the story which was different to mine in a small way. But she took it in a very big way. We said game, she said bet. As if we were to bet. Its stupid. I backed out after the first day! what the hell? She msgs me calling me a lier, and I used her and took advantage of the friendship. Explain how I took advantage of the friendship? Her showing me half naked pictures of herself being advantage? You're the one with the boyfriend and you're showing me, I didn't force you. I don't force people. Thats just pathetic. I admit I was rude, but she was too, not considering my feelings or anything on my behalf. Just hers. She wants me to leave her a lone. I don't fucking understand what the fuck I did. Then it comes to her and the time of the month. Period. She's moody. Thats the only thing I can think of. She needs to learn how to consider other peoples feelings/thoughts and try to work with them other then forcing her own opinion in to everything. Shes going to get into trouble like that like she did right now. She insist on being right, where I just walked away because I didn't feel comfortable walking with her and now its my fault. geez, small thing that could have been avoided turned into something fucking big. Get the fuck over it!
Greg said he'll fix everything, he's basically the link between me and Coco now. He said that we both dont seem that there anything wrong. So theeeeeeeeeeeeeeeeeeeeeeeeeen tell me what the fuck the problem is? Did she get some sleep and her period magically just fucking disappeared? Fuck my life, I hate girls here. Why can't I just know someone some what normal and considerate. Uni is going to be hell tomorrow. Apparently we're going to talk it out.... I'm going to say the exact same shit here, minus the period because I know girls would get super offended with that crap.
