Need to know if this is true: am I emotionally abusive? I’m in a terrible situation, being accused of being a female abuser!

I have had trouble with my 2 year relationship and have recently discovered I am an emotional abuser. They said to me that I am emotionally abusive…. To my memory I have never been abused in any way. I recently broke up with my boyfriend because I thought I “didn’t feel the same” as I had. Is it possible that the recent diagnosis could be causing me to think this way? I am so confused. Am I emotionally abusive? And, besides is different?
