Those are just red flags.
And ive had many conversations with people on this site about photo sharing and everyone has their own opinion on it. But I live in reality and I also recognize that its 2023. My personal feelings is that you should NEVER send photos and videos to strangers. I highly recommend doing a short chat online to just get general questions asked and answered and then you should schedule a video call ASAP.
On that call, you should have some prepared questions to ask. I have been doing this for a very long time, and I also train and coach couples and single women, so I have a full training program already laid out. For me, I am just following a model that works. I know the questions I need to ask, I know the answers I'm looking for and I know the level of seriousness and committment I need from people.
I have had couples be "VERY EXCITED" to start working with me, but then 2 or 3 weeks later forget about their life obligations. Thats why I make sure people tell me their schedule for the next several months and not the next several weeks. What you will find is that most people, maybe 90% of people are "in the moment" and have no interest in long term.
That's not a red flag, but just be aware if you want someone ongoing and long term, you need someone with time and the ability to sustain communications and interactions.
Good luck guys in 2023
