First I'd like to mention, I am not as articulate as I would like to be when it comes to advice or conversation, I am working on it little by little. However, I would like to offer a bit of advice as I have been in similar shoes of the girl you're interested in/dating. If she's sending you mixed signals and your friend said she's jaded about past relationships having any sort of thing with her will most likely be overly complicated. We all have been hurt at least once in a relationship, it's how we deal with it that either makes or breaks us. No one wants to walk around jaded,broken or scared, most of us probably don't realize were hurting others in the midst of building up our walls, as she is with you, now. This is my purely biased 3rd party opinion, it sounds to me as if she needs time to reflect, regroup and refrain. Reflect on why who what when where and all that jazz, regroup her mental and emotional stability cuz it's clearly not intact if she's hot one day and cold the next, and refrain from jumping into any new beds or hearts and relationships. She may or may not realize it but she's trying to gain back some of the control she lost when her heart was broken or she was fucked over (cheated on). It's like trying to prove to yourself that you can control how and when things start and end or something since she didn't get if she was cheated on or broken up with. If that that makes since. Idk I could just be projecting so take it with a grain of salt. All in all, I'd say "nope" to dating her. I've walked miles in her shoes and I wouldn't have dated me either when I was acting like that. Treat others how you wanna be treated, right? So if she didn't like being toyed with, why's she doing it to you and your emotions so much so that you're asking for strangers to help you decode her bs? How can she respect you if she won't be straight up and tell you how she feels, you're not a mind reader. Red flags everywhere. Dude, she could have asked you out, why did she wait 2 months for you to ask. That is so dumb. That is really really dumb. TLDR: I know you like her but if I were you I'd cut ties. I see Red Flags everywhere. Get with someone who knows what they want, goes for it and treats you how they want to be treated. You know like a good person n shit. :)
