Lost I'm afraid all that would be a dealbreaker for me too. I was seeing someone last year who had their 3 year old every weekend and it quickly became too restrictive and complicated - I was doing all the compromising because he was 'tied'.
It could depend on your own situation too though; I don't have DCs and my free time is my own which is why I want someone in the same situation who has plenty of time to spend with me getting out and about, going away etc.
Mr BBC is still messaging, he's definitely keen. Sod's law... I'm still talking to him though, I do like him, just not really in 'that' way.
The other two irons could both be very promising though, if we can get to meet up stage - Mr Mountaineer and Mr PhD.
