Help! Need advice on how i can help my friend

Hi to the 7cups community. Just want to say thank you ahead. There are always listeners here for support and i am so thankful a communityblike this exists.

Was just hoping to find different perspectives on how i can help my friend and perhaps figure out why her actions are so.

I have this friend who keeps drunk calling an ex. And then the next day she feels so much regret about it. But then she would get drunk again and drunk calling again. Personally i dont really drunk text/call so i dont understand why she does this. But i think this way is not exactly emotionally healthy. So i hope to be able to get a better understanding so i can be of better help/advice to her.

I look forward to your inputs. And i hope everybody who reads this have a great day ahead 😄
