I don't know if this is a situation which calls for blunt honesty, or for letting sleeping dogs lie.
I got chatting to this woman through a mutual acquaintance a few months ago, and we ended up arranging to take the kids out together. We get on very well, as do the kids, so we've met up again. And again. And again.
It's a nice thing - but I've become a bit concious of how intense the friendship has got - both in the frequency/length of interactions and the range/depth of conversation. If she was a man - I would have backed off a long way back out of respect for DH.
I have a sense that she's maybe in a more fragile place than me - so I want to make sure I don't end up somehow hurting her.
Should I
a) consciously cool the friendship for no outward reason
b) have a hideously embarrassing conversation
c) keep on with the new-best-mates schtick and hope it'll settle into a great long term friendship with a lovely person
