To be fair, in the world of OD, I think 6 weeks is still early days. If I met someone IRL I'd expect it to be exclusive and to trust it was what it seemed early on. I'd certainly never multi-date in the real world.
But at the same time, 6 weeks isn't one date. And if someone said to me after 6 weeks of dating that they wanted us to come off the site, I can see how I could feel tempted.
Don't feel you've got egg on your face though. It's one of the rules remember? People disappearing and going wierd on you and shit isn't your fault.
There's nothing wrong with wanting to be loved. I don't know how much of the previous threads you've read, but I have a real issue with 'love'. I'm beginning to think I'm no more capable of loving someone else than I am of being loved by them. But it doesn't stop me from wanting it. It's part of being human.
Dust yourself off, get back onto the site, take a step back from it emotionally and just enjoy meeting new people and have some good nights out. If anything else comes of it, then that's a bonus. Let some people buy you dinner/drinks and tell you you're beautiful. Why not?
