Libel: Being Accused of Copyright. and Slander/Libel

My question involves defamation in the state of: took a photo on my phone of step daughters wedding. I posted it on Facebook the day after wedding after bride and groom said was ok for all guest to do so. Photographer messaged me on Facebook the day after that stating I had stolen 'her' photo and she would sue me for copyright. I took down the picture as to not upset bride and groom then messaged her back stating I had removed it but in fact I was 'my' picture and have proof I took it. I then proceeded to ask for advice on a wedding page on FB from other photographers and posted a copy of her message (but crossed out her name, as did not want to name her) to ask if what she had wrote to me was the correct way to go about it and also if I was right in thinking that if I took the picture... It in fact was 'mine' and no copyright had been breeched! She then has proceeded to write to me saying have slanderer her and she has reported me to police (so she says)... I did not reply but did delete the post on wedding site. She has then since has sent me another 7 messages being nasty saying that I'm evil and that all my family hate me... Laughing at me and gouding me. Still I have not replied. It is slander/libel that I have posted what she wrote to me?? I have not lied about her and have not been personal, not even named her?? Where do I stand on this?? Thank you
