<human>: My ex is really an exceptional girl: kindhearted, supportive, smart, hardworking, sexy with huge sex drive … We had wonderful time together but it's over now. However, we still like each other as friends and are in contact (I'm in touch with most of my ex's). She usually asks me about my sex life and I have no reason not to tell the truth; after all we are old friends.

Now I date with this new girl for a while and my ex always asks how things go on with my new girl. Sometimes she advises me as well. First I thought she does it only because she likes me and cares about me. But recently I'm a bit doubtful about her real motivation behind all these because she is bisexual and asks unnecessary details about my new girl. The other night she asked me again how things go on with my girl and I said nothing special. Then she asked to give her my girl's number. At first I thought she's joking but she said she meant what she said. I didn't give her number of course but I'm wondering what I should do because I know my ex has absolutely no standard on sex topic and it's not that hard to find someone's contact info these days.
