Conversing off the dating site

Hello again, and before I ask my question, i’d like to thank all the ladies who answered my last topics. I apologise if I didn’t reply to some of you, but being a single father and running a business give me very little time to check in here. This question is for a friend in the USA.... He signed up to a notorious pay per letter site and was obviously scammed. He has planned a trip to Ukraine next month and the woman disappeared once she pushed her to leave the site. I have explained how the woman I met behaved once we left a site like this. We video chatted once or twice a week on Skype and whatsapp. Talked on the phone often. Shared hundreds of pictures and videos of our lives and sometimes chatted 8 hours a day before I come to visit her. I would like to explain to my friend that a genuine woman doesn’t behave like the one he met and would like to hear what you would expect from a man who you like, once you started chatting off this site. How often would you like to video chat with him and in your mind what’s the importance of chatting face to face video chat? Would you like him to call you every day or even every week on the telephone? How can a man who has never had experience taking to a genuine FSU woman tell if she’s genuine, by the way she corresponds and interacts with him? What level of communication should he look for, if a women likes him and she sees him as a potential future husband? I’m trying to get him to join this site where he will have the chance to chat with nice women who are serious about meeting a man.... women like all of you. Thanks )
