We have known each other online, for ten years.

She told me years ago, that she has PTSD.

She has always been critical of me to a certain extent.

When I had re-installed Yahoo Messenger on my computer, in April of 2012, after keeping it off my computer for nine months, she 'raised the roof'

, wondering where I had been for so long.

While I know that my removing it without telling her wasn't the smartest thing to do. I have often wondered, if she felt abandoned when I didn't tell her in July 2011 of my intention to un-install Yahoo Messenger, and if her criticism in general is her way of saying she is jealous because I am not in a relationship with her.

She denies that is the case. But she repeatedly, has cut me out of her life. Only to contact me just a few days later, accusing me of ignoring her. She denies that is the case. But, I am wondering, if she is afraid both, of abandonment, and has trust issues. Over the last ten years, one of us has been in a relationship when the other one wasn't. So, We have never had a situation until maybe now. (I think)She recently broke up with her boyfriend of four years.

Her criticism while foul-mouthed, she has never called me a nasty name. So, That is why I am wondering.
Any feedback would be greatly appreciated.
