Difficult situation.
I recently invited an old friend to join myself and a group of my friends for drinks this evening. She only knows a few of them having met them once or twice before and the others she hadnt met. I must say i was quite embarrassed by her behaviour. Constant sexual references which actually came across quite vulgar rather than funny. Icing on the cake was a story she told about sleeping with recent ex in a restaurant with every risk of getting caught. I was horrified. She has been going on lots of one-off dates with men she has met online and has been sleeping with them. Tales of things she does during sex. I am concerned about her but also angry as i feel she showed me up. Do i confront her about this when i see her alone next week? I am terrified she will do this at my wedding (next spring) and quite simply very concerned that she is putting herself at risk, emotionally and physically. I am concerned that this is bravado covering up low self esteem but she is ultimately selling herself very short and i dont think a good friend should say nothing. Would be interested to hear peoples thoughts. We are 29 years old to add context.
