Am I in the wrong?

So my friend and I are not friends anymore I guess as she just randomly stopped talking to me for 2 weeks and didn't tell me wheat was going on I thought I did something? So I told my other friend what had happen just looking for some support and reassurance I did not say anything bad or hurtful toward the other person. She has now found out I told someone and is bringing up what the issue was and it's coming across as she thinks I told people her personal business which I didn't and is saying I'm in the wrong and I'm the one to blame and I stabbed her in the back and she only told me what had happened cause I consistently asked (I asked about 3 times within 2 weeks) I was concerned and worried I had done something I personally think we are both in the wrong but more on my part as I didn't have to tell others what happened but at the same time it affects me as well and it's not like I told them anything personal.
