<human>: Provide a brief overview of the text.

We have been together (in person) about once every 5 months and she was very excited to see me even up to 4 hours before she arrived at my house.

But once she arrived, she got very nervous, distant both physically and emotionally, and proceeded to say that this can not be normal and that our relationship must be a mistake if she feels this way, and is sure that no one else has been like this with a partner of theirs.

Asides from this one day, we have spent up to 6 weeks together at a time and she does not feel like this all the time, just in short bursts at random time with out any provocation.

Is this a experience anyone else has had?
