You might try giving yourself more credit. The biggest mistake people make is in trusting too soon. You're not supposed to lavish trust on someone just because you're attracted to the person and they seem to like you. From what you've related, I wouldn't be too quick to trust her myself. In her mind, this relationship is still in the stage where she is "sampling" you, rather than being all that serious about you. She sounds like a young woman who is pretty forward and likes to "try guys out." Maybe it will go somewhere, and maybe it won't. You'ld be wise to step back a bit and be less ardent in your pursuit of her. She's taking you for granted because you seem so needy of her. Go quiet, and let her wonder what you're doing.

If you've had a history of being hurt by women, maybe you've been investing too quickly and too heavily in women you should have moved on from sooner. Maybe you're too available. It may be you're catching the attention of the wrong types who feel you can be had for the asking and discarded when they have other fish to fry.

I don't know her. You value the relationship and want it to continue. So carry on. But stop assuming that any problems between her and you are the product of you being some kind of head case. No doubt you've got your internal issues. Who doesn't? But I think you're overly quick to see yourself as defective and in need of a psych-overhaul. Don't idealize her. She's got faults.
