Just recently my girlfriend and I hung out with a friend of ours. We played video games all night, and I fell asleep early. I woke up the next morning and everything went as usual. After a few days, I learned that our friend had asked my girlfriend out on a dinner date, and when she asked about it, I had said "Yes". Now I learned that my friend and girlfriend have a small crush on each other. My friend said that he was sorry if it made me mad, and I said that it didn't. What I'm asking, is there something wrong with me for not being mad that a friend had a crush on my girlfriend?
