Hi,
I'm having trouble with one of my groomsmen. He is the only one of my groomsmen who hasn't gotten fitted for his tux, and whenever I ask him to do it, he gets very defensive and tries to give me a list of excuses to not get fitted. He had also invited a guest (whom neither my fiancee or I know) when my fiancee and I had already asked our wedding party members to not bring guest since the guest list is already bigger than expected and we want to keep the costs down.
How do I handle these situations? He is one of my best friends and I don't want to kick him out of the wedding, but I also feel like he isn't respecting the wishes of myself and my bride-to-be.
