Can we have a split of the thread, so that people who wanna condemn this behaviour have their own thread to do it in, without ruining the thread of the Op? Especially since he hasn't asked for a judgement from the crowd, just insights into what might be going in in her head from other ENFPs?
"Me, me, me!!!" is what is going on in her head. OP needs to quit deluding himself. Going to the source is unwise as well; OP only got indiscernible, long,winded, self-important psychobabble that compounded the already shitty situation.
Gonna have to agree with Duck on this one. She lost her source of affirmation and detached when what she had no longer sufficed. I wouldn't go as far as to say that she was cheating, but she probably developed feelings for someone else. If OP moved on, she would probably take notice but I don't think she would approach him in the same vein as she had been in the romantic stages.
A man builds. A parasite asks 'Where is my share?'
A man creates. A parasite says, 'What will the neighbors think?'
A man invents. A parasite says, 'Watch out, or you might tread on the toes of God... '
I'm conflicted on this one, to be honest. Her behavior seems erratic and I can understand why people are suggesting that she's trying to use you and might even be cheating on you. I'm not going to discount those suggestions because they may very well be true, but for what it's worth, I do think people are bringing some of their personal baggage to this thread.
Personally, I think she sounds very insecure. Did you try to initiate contact at all during the ten days you were away? She might have freaked out that you weren't getting back in touch with her as often as she wanted. I don't think you did anything wrong and she shouldn't expect you to be a mindreader but some people do need a very high level of contact and communication in order to feel safe, and one moment of panic can spiral into all sorts of twisted thinking about the relationship itself.
If you haven't already talked this out with her and aired all your concerns as you have with us, you should do so. Don't let her weasel her way out of resolving the issue just because it feels more comfortable not to.
When I was around 18 I did something similar to a girl, and it was for certain resultant of personal problems I am still unwilling to discuss.
Interpersonal relationships can become fucked up for reasons well beyond your immediate comprehension. Endure the emotional torture or abandon ship, I reckon.
(also, a lot of the advice in this thread is just flat-out bad in terms of "what is causing this", although I agree on the suggestion of you dropping all emotional investment ASAP, provided you don't possess a super-human will)
Once you defer from unadulterated attraction/affection and into the netherworlds of speculation and persuasion things go down the tubes (granted I'm a different animal), so if you value her traits enough to start an internet thread, learn to identify them in others and take what you want, op.
