It was out of control.
The night had not gone to plan and I was panicking.
The deal was that she could flirt with another woman and if she got a snog then fine I could live with that.
But this was more than a snog, I was in the back of the cab with Sarah my girlfriend of two years and Hannah, our acquaintance of a little over an hour and they were both half naked and I didn't know what the hell to do.
I should explain. We had been in New York for two days after a late decision to get away and see if we could rescue our relationship.
You see I'd been naughty and I'd been caught and Sarah was in no mood to forgive and forget.
Back in London I'd drunkenly slept with a mutual friend.
I regretted it and Sarah knew I loved her but she was hurt and that's fair enough.
So now my credit card had to pay for New York and Sarah had to decide if I was worth another chance.
The first night we got drunk in the hotel bar, had some great sleepy sex and awoke on our first full day of the trip feeling pretty good.
First stop was MoMa and we stayed most of the day. Wasn't really my scene but I wasn't really allowed to make any decisions so that was that.
In the evening we caught the subway to Battery Park Gardens and settled down to dinner overlooking the harbour. Again the beer was flowing and we were having fun.
Until Sarah caught my eye staring a little too long at the waitress and then she started to talk.
It was so calm it was eerie and it was so intense it made me cry.
She loved me, she wanted to be with me but she couldn't trust me and she didn't know what to do.
I started to blub my excuses but knew as they left my lips they were pathetic.
Sarah told me that we both had to change, both had to be more honest and both had to learn that nothing could hurt us if we were.
Then she told me that looking at the waitress and imagining kissing her had soaked her pussy – and I dropped my fork in shock.
