We got engaged two nights ago. Today we went to out favourite cafe with my DS and the lady who runs the place was so overly friendly towards DP that even DS noticed. It's put a bitter taste in my mouth and I don't know whether to say something. He obviously goes there with business partners etc every so often but I think that it takes two... He seemed normal whereas she was giggly and butting into the conversation. Not sure what to make of it???
