My apologies to the OP, we've hijacked your thread.

I'm talking about deciding that you're a couple.
The OP was asking about how to get a conversation started in the first place, but once you've got past that point and realise that you're getting along quite well and the other person maybe fancies you back, you can't just assume you're a couple now. Even the British have a conversation about that.
One of my friends tells it this way. She had been getting to know this guy in a group. He invited her for a walk in the park just the 2 of them and asked her, "do you want to go out with me." Here's your British term. We don't date, we "go out" with people. But that means you're boyfriend/girlfriend now. Well for them it did. They're married now.
I never get past the spending time together. The bloke usually bounces off and starts going out with someone else and I'm like, oh ok, that's the end of that then.
