allnewtome Hello and welcome!
I don't know, I think you can probably go to a fifth date (without sex) before you have to make a decision. I don't think it's on to be sleeping with 2 people at once, or making any sort of emotional declarations either.
I find that the 'what are you looking for' chat is a pretty good one to have very early on (first or second date even). I was always honest that I was looking for a 'boyfriend' but not a 'partner'; so someone I could go on dates with, laugh with, hold hands with, have sex with, even fall in love with, but I wasn't looking for someone to move into my family or my life. I'm not interested in conversations about whether the guttering has been cleaned or whose turn it was to empty the dishwasher or not. I wanted it to be like it was when I was 17 - all of the fun and none of the responsibility...
Someone ended it with me because he did want all of that; but I also didn't get past a second date with someone who told me he didn't want to be monogamous and that wasn't ok with me.
If you're all honest about it, that works pretty well. So I would open it up from that; "so what were you looking for from OD?" type question.
chick Well done!! Onwards and upwards now. Are you celebrating 
Maisie0 What should he have done then? He'd have had to end it with Steel at some point. Either that, or continue seeing her when his heart was no longer in it and deny her the opportunity of finding someone who really wants her; or carry on seeing her whilst withdrawing emotionally and torturing her with all the worry about what she'd done wrong and why he'd gone cold. Of course the person who is left will always be the one who is hurt but there's no way of avoiding that.
