Am I in the wrong or right?

Me and my girlfriend were walking in the park together, we often don’t get out much. My girlfriend family member called her and while we’re talking and she asks me can I get this call so I said yes, after the phone call I said that was rude and she got angry with me? and kicked off with me?

am I in the wrong or right? She did speak with this family member the day before?
