Ex-girlfriend confusing situation
So me and my ex went out for a year and then I broke up with her, and we were "in limbo" for several months after that where then she asked me out again and I told her no because she was still too needy and dependent on me which was the reason I ended the relationship in the first place. A few months after she asked me out again, she called me out of the blue on my birthday and asked me if I wanted to do brithday dinner so I said yeah fine and we went, and we've now been talking for the past few months ever since. For the first few months after that I thought she was sending me mixed messages and didn't know what she wanted, whether just friendship or more, and eventually I told her she was sending me mixed signals and asked her what she wanted from me and she said "nothing", which made no sense, as such as the day before when she sent me a text that said "youre amazing, i love you", which apparently she sent because she has a huge fear of heights and thought she would die going down this mountain. I stopped talking to her for her mixed signals, and a few weeks later she started texting me the "i miss you" a couple times, and we eventually reconnected and hungout a couple times which went OK. A week ago we hungout then and started making out, which she claims only I initiated, which is untrue, at least to the extent that after that she kept trying to hold my hand and we held hands for hours. A couple days later she called me and asked if I wanted to talk about 'something' and I basically told her id be interested in dating her again, taking it slow, or at least trying to go on some dates, she said "i dont know", said she had to figure out her work and life situation right now, and that although I'm someone she could marry someday and I make her a better person, she didn't think it was a good time. She said I'm her "mr.Big", a reference to a sex and city character that can't commit but who is meant to be with the main character. So she said I was just lonely and want 'somebody', not necessarily her, which I realized since then is somewhat true, and why I must agree with her decision. She said she would 'think about it' regardless, told me to wait, said she just had to figure stuff out in her life, and couldn't just date me casually because she cares too much about me etc. I said these are understandable reasons and its true that I should think about whether I really want to date her as well or not, and we left it at that. What's strange is she also said she "didnt see me romantically anymore" which bothered me because I took it as that she wasn't attracted to me anymore? But that wouldn't make sense, considering everything else she said? Anyway, a few days later she called me at 2am after a bar saying she had no place to go because she lives far from the bar, asking if she could crash at my house. I told her I was at a friend's house, the truth. The next day she called me to get lunch, which we did, and it was friendly and we got along as usual. The next day she called me at 4:30 am and I didn't answer because I had work the next day. Apparently the next day she told me that again she didn't want to drive all the way home after the 4am bar and wanted to see if she could crash at my place. I was like "oh?" "i thought it was a drunk dial", it was past 4 am. Apparently she "wasnt drunk" either. But sobered up in her car before driving home. I agree that me and her shouldn't go out, but I am just wondering that with games or confusions like these, is she even worth being friends with? We are close, to the extent that we have remained friends through everything to this point and we care about each other deeply. I just feel that in the past few months she has been playing games and acting selfishly, but id like an objective opinion on whether her intentions are good. I also sympathize with the fact that I broke up with her and then rejected her a few months later, which my friends say is why she had to play games to try not to seem desperate and get me interested again. I'm just not sure where to draw the line as to whether its worth my time to keep on with this friendship and future romantic possibility. I should also mention that she frequently attempts to make me jealous by talking about other guys she has had interest or sex with, although she is single. She also refuses to make plans with me, although I am a busy person, and insists on calling me on the spur of the moment to hangout within the hour, which I have told her I do not like.
