I told a friend about my relationship problems

And now I feel I have to stop contact with her because of the embarrassment. She is not the best friend, but we occasionally meet for coffee and she knows the whole story since the beginning. She gave me very strong advice to leave him and I was emotional, so I said things about him in a very explosive way. It was not cheating or anything huuge, but I just felt I lacked the emotional support from him and my feelings were minimized all the time. We worked things out and now she has been inviting me for coffee and I have been dodging. I don’t want this judgement from her when she asks about him, but it’s totally my fault and a big lesson to never do this again.
