Here's what happened, I met a girl in class and she's pretty cool so we chatted then a week ago she told me she has manic depression and tried to commit suicide..I was pretty shocked but I said that I still liked her, she gave me her # and I called it (on same day) but no response..then next day she said she had work and couldn't pick up. That same day she got some other guy to hang out with me and her, and was into him but I knew she likes me too..Then after school I asked if shes going to take the bus she said yea, then after school she changed her mind and decided to take a taxi (rejecting the other guys offer to give her a ride) so I said ok bye but then she offered me a ride with her on the taxi. Then we talked some more except I got sort of stupid and pulled this joke: "you cook and have a job, marry me..just kidding". I found it funny I guess she didn't though. I asked her when she would be free and she just said that she has a lot of work and then when she gets a week off work she's going to do volunteering, so I guess no time for me..Anyway when the cab got to my house I gave her a hug and she just started at me when I left..What's this girls deal? I know I've been moving a little too fast but she still appears to like me..but then whats the deal with the other guy. Could anyone shed any light on this situation?
