Its the sudden turn in behavour. She was never like this in the 2 months i was seeing her. The only thing i did to her that was negative, was ending it twice with her and saying i wanted to be friends. I never displayed any other negative stuff. Like i said, its the sudden turn in Behavior that kinda freaked me out. Im getting conflicting things from people about this, im confused myself. Some are saying they think i was getting played when i tell them, others that there is nothing suspicious about whats happened. So i dont know anymore. I guess i just want to know whats happened so i can move forward.
Okay... take a deep breath. Okay... do it again.
I understand a lot of points that were made in this thread from everyone and that's a wonderful thing.
First of all -- I know all about sudden change in behaviors. That's scary for anyone that's close to someone or cares about someone regardless of the type of relationship or even the personality type. Any good person is going to want to figure out what's going on with the other person and if their gut is telling them something is "wrong" then that's it. A gut instinct is something individual and it can't be typed at all.
So yes, it might have appeared badly and over the top for you to drive by her house, but I think you still care about her no matter what happened. That's the way life actually works for people sometimes. I know myself there's people that drive me up the literal f'n wall and yet after I vent or after I let off some steam I still do something that's seen as caring. This is all personalities aside. Sometimes people just feel that what's right for them is to be of help to others even if others don't deserve it.
The other side to it is that you shouldn't ask her what she did the night before when you know that you might catch her in a lie. Do you understand what I'm saying? I know it happens, so what you did was a human reaction for anyone. I've seen people in my life through the years who get jealous and upset even if 3 friends went out and didn't invite the other one. I've even felt that way when I was younger. The thing is, knowing the truth to your question or the lie to your question most likely isn't going to make you feel good. So in short, don't ask if you can help it.
On another side of it -- she's young. I don't think she even truly knows what she wants or understood completely what you were to her or that she does and like I mentioned to you earlier -- she just wanted to keep you around for when she needed/wanted you.
Personally as a person (maybe that's INFP related as I've read a bit in this thread), I don't want any man up in my business. I have my own life and my own interests. He can come along for the ride, but every waking minute of the day is not going to be dedicated to him. That is not how I function at all. If I can't be myself with a guy... it's not happening. Of course when relationships are new I'm sure it's the "oh gee I want to see him" or "oh gee I want to see her" I imagine for some people, but once that phase is over...you have your own life and I have mine. We'll meet up every day (if we're marred) or a few days a week (if we're dating), but you can't crowd me and I most likely won't really care about every single waking moment of your life so long as you're not out there being... like a criminal or you have some weird addiction/obsession.
I understand how that does get hard for some people though. I have friends... they're not even INFPs nor do I even know of their personalities and they've forgotten who they are because of the guy in their life. We can't even hang out because they don't feel content without the guy coming along. So if this is something that's hard for you grasp, I truly do feel for you and I accept what might be a need.
Still -- something IS up. I don't know what kind of relationship she had with her ex, but if she's jumpy near her phone... is she afraid of him? Was he abusive? What really is the story and why can't she bring you around her parents? That's just... that's not even INFP related I can't imagine. I don't think it's any kind of personality relation either. I think she's just afraid and she's confused and she's immature.
