Hi, I understand your dilema. What I've decided to do (and my husband agrees) is I would only have a language exchange (I use WhatsApp or Skype) with other females. I also have decided that the language partner had to have a photo displayed and I usually write back and forth a few times with the other person to establish the time difference between our countries and if we can agree on a date and time that works for both of us. I don't give my phone number or ask for theirs until a first appointment is agreed upon. I know I'm excluding many potential interesting conversations by being so selective, but it's working for me. When I can't arrange a free language exchange, I look for a similar conversation partner within the community tutor pool and I book and gladly pay the fee for an hour long conversation with a native speaker. Best wishes, Kim
