Is she crazy I feel she must be?

Okay so this is a long long question lol. I met this girl off of gay.com. She lived like a million miles away from me but to be honest I didn't care. The connection was so strong that it didnt bother me, and I knew that she was planning on coming to see me in less than a month (ticket already bought). So the realtionship continued and I asked if she would like to be mine and not see other people. She said yes of course cuz i'm totally adorable n such :) Soooo time went on and I caught her in a few white lies after which I explained to her that honesty was really important to me and even more so because we were so far and I only had her words. Sooooo time went on and everything was wonderful until one day. She was online talking to me, then told me her friend was having a nervous breakdown (she is about to get her MA in psycology so a lot of people turn to her) I said i could let her go and she said she would call me asap. Sooo two hours went by and I was home alone and got really scared and anxious over this story about a guy in the area going crazy..long story short I thought that 2 hours might be long enough to call her, I call and she doesnt answer I though to myself well she must be on the phone with her friend still... she was still online so I asked her in an IM if she could talk to me online just till I wasnt as scared..still no answer. Well 7 hours go by and 3 more phone calls with no answer. I go to bed and call her when I wake up and ask what happened. She told me she fell asleep while waiting for her friend to call back.. then it turned to well me and her started talking about how far away you're going to be moving ( I lived in FL and was moving to CA and she was on the East Coast)..I said I understand THEN it turned to She was on the phone with her ex the entire night up until she went to bed. Now this is the same ex that she told me had sent her a myspace message a few days prior..an ex from 10 years ago. I was excited and told her it was awesome that she got in touch with her and she shold catch up. I am very very understanding and the fact that she had lied to me once again really ticked me off! SO... I got really pissed and didnt talk to her for hours while she blew up my phone.. I finally gave in to one of the calls before I was calm and said a ton of hateful things to her like I didn't love her n such. She kept begging me to give her another chance up until I went to bed. The next day I called to say that I was sorry because I shouldnt have said those things and she told me she wanted nothing to do with me... that I hurt her too bad. This is 8 days before she is supposed to come and I couldnt handle the thought of not touching her so I ask her to come... she says give her time to think about it then says she won't come. I am totally devestated. I had never felt this way about ANYONE. But I leave her alone... she calls 2 days before she was supposed to come asking if I still want her to come..I say yes. 2 hours later I get another call telling me she cant. I am royally hurt now and decide to leave her alone for good because I felt that she was playing with me. a few weeks go by and she is texting and calling not a lot but often and im ignoring them all... then she IMs me asking first and this is all in one IM Are you not talking to me at all now? second sentence is Are you really ignoring me? Then My mother died today. Now the entire time she has told me that her mother was sick but it sounded odd. I still cared so for about 2 more weeks I call every day to make sure she is okay blah blah blah but she never talks about it and when she says things like she is stressed and I ask why she tells me about work and how crazy it is. Nothing about her mother. Well about a week ago she tells me that she is with someone.. after all the excuses about not being able to be in a relationship with not just me or anyone, I mean. I am at a loss! It hasnt even been a month since the whole LIE happened and she is already with someone even after her mother "dying" My question is and im sorry it took so long to get to... IS SHE CRAZY?!?! was this all a game. I mean my roommate says she is into psychology and she probably knows how to get into peoples heads but I thought what I felt was real.... HELP!?
