<human>: Can you provide a brief rundown of the text in within 3 sentences?

The initial break wasn't actually that bad, as we were good friends for a while before we dated (and it was the classic "I'm not in love with you anymore, but I love you as a friend" thing, so I tried to play it off like it was fine). However, as time went on, we grew apart for various reasons, including (but not limited to) my inability to interact with her without feeling depressed, my (sometimes less than well-mannered) reaction to the breakup, and my realization that there were, in fact, a *lot* of things that I did not like about this girl.

Anyway, one thing led to another, and it came time for me to tell her that we couldn't be friends to the extent that she wished (for my own good, really). She reacted... poorly. Basically, she went into a huge rant about why she never would have continued being in a relationship with me, and how she was glad she never had to talk to me again. And she used a word... "manipulative".

Honestly, that word hit me extremely hard. Never in a *thousand years* would I want to actively manipulate somebody, in fact, I don't even think I could. I'm a really shy person with a lot of insecurities, and I'm generally very passive. But when she called me that, it made me think a lot, and that's where I need help.

Could I have been manipulative in that relationship without noticing it? I don't really know if I would even be able to tell. I'm just extremely confused and I want to stop this behavior *immediately* if I truly am manipulative towards my SO.

 Any advice or help is welcome, sorry for how long this is.
<bot>: My ex told me out of anger that I was manipulative in our relationship. I certainly didn't try to be so, and it is really bothering me that I may have done this without really ever knowing... help?
