Can this be possible.

[VIDEO: "What is parental alienation?"]

She comes to visit. Spent a nice couple of days together. Decide to do a picnic. I let her pack the picnic at my place so I can’t be accused of controlling or not listening etc.( yes I’m an expert now at accommodating ) we drive to the beach singing and laughing …so far so good. Drive around. Looking where to set up. She suddenly turns to me and says. ‘ I don’t want to do this’. I know the tone, the energy, the emptiness and the look all too well. Annoyed but silently I drive home , empty the car. Day ruined. She leaves. Says she has to go. Says never wants to see me again. I tell her I can’t do this either.
A few weeks later she is back ( silly me) and I ask her about ruining  such a fun day. She doesn’t remember why she felt the way she did or what triggered it, didn’t care that it hurt and annoyed the heck out of me , but said her feelings are always right.  Then dismissed it as not important by her lack of interest in it. Like it was a trivial thing.
Is this what they do. This is bpd isn’t it ? She isn’t diagnosed. But I’m pretty sure she has it. A psychologist once told me you have to love them perfectly. In every way in their eyes. One percent not perfectly and you are done.
It make me feel I’m going mad.
Any advice or comments will be appreciated

I would add to that comment about loving perfectly- it is also possible that perfect isn't attainable, because the issues involve the other person's feelings. We can't control what someone else thinks or feels.

Pefect isn't attainable because, no human is perfect. Any two people are going to have differences and disagreements at some point. In an emotionally healthy relationship- conflict isn't all the time but when there is, each person has the ability to resolve them.

It is confusing when this turn around is out of the blue- you think things are going well, and then suddenly not. Why this happens, it's hard to know what is going on with the other person- but what you do know is that it did happen. Maybe it's BPD, maybe not- but whatever it is, you saw it happen.

Why she doesn't remember it? It can be dissociation- where the person is so flooded with feelings they have difficulty recalling what happened, or it can be denial- where they compartmentalized it, or shame avoidance. However, not remembering or not being accountable is problematic in a relationship.

What you can control is your own choice. If you are in this section, then you are moving on from the relationship. That you wonder, question yourself, that is a normal response to this confusing behavior. It may not be possible to know why she does that. It may not even be about you or anything you did or didn't do. Sometimes there's no closure with this, other than the closure you give yourself.
