Am I wrong for how I handled this situation with my girlfriend?

I stressed to my girlfriend that I wanted to talk with her in the morning the night before and she agreed. Morning comes I ask if she wants to talk soon she said it's too early to talk 10 minutes later she gets a call from her friend saying she needs to talk to her, not an emergency. She then spoke to her friend and I felt disrespected and that she put her friend first before our relationship and made that clear. Side comments were made by me , I then chose to workout to relieve myself and apparently the noise annoyed her with my machine so I tossed it on the bed. She told me if that happened to me she wouldn't see why she would be upset. I accepted that I was wrong and got over it. She is still upset and told me she didn't want me to visit her grandpa with her at the rehab center. Also didn't kiss me. WHOSE WRONG?
