Hi to all the newcomers!
THIS is what I've learnt from posters here and my own experience:
I've learnt that if they seem to be losing interest as haven't been messaging as much then your intuition/instincts/gut is usually right.
If they aren't replying to messages with in a timeframe that's acceptable to YOU but you can see they are online then they aren't making the effort and aren't worth your time.
Similarly if they are online and aren't chatting to you or are quiet for a day or more, especially if you've already had a date, then they aren't making an effort to keep you interested and get to know you so they aren't worth your time.
If you've been chatting for more than a week and there's no hint of a date then they are wasting your time or too shy to ask. Ask them to meet and take it from there.
If everything is message based with no move to progress to phone call then I personally can't be doing with that. Chatting on the phone separates the wheat from the chaff in my experience.
Most of all I've learnt to listen to my gut. My gut has anyways been right but I've stupidly chosen to ignore it.
I've previously been too generous with my time, my affections and my money and now won't invest more than the other person is investing in things.
I'm harsh, strict, whatever you want to call it but I won't tolerate any twats or bullshit anymore. I know my worth and am holding out for someone who is worthy of my time, love and affection.
