Thanks for all of your replies. I wrote this in haste out of feeling rather ticked. I still am; mostly that I wasn't consulted. It is so rare we have a difference of opinion I am sure he just assumed I wouldn't question this. Fortunately, it worked out. The boy was taken off the street and reunited with his father. Given time to decompress and think more about it I find my appreciation of my boyfriend has actually gone up with the realisation that friends to him matter deeply. If it were my own children in crisis, knowing he would stand up to help is great comfort.

Still, he ought to have consulted me over this rather than springing it upon me.
