So my boyfriend tells me he is going to dinner with his friend that is female. I'm not a nosey girlfriend and I trust him, but the closer it was getting to the day, the more insecure I felt. I had never heard of this friend before. The only women he talks about are two that I have met that are in relationships or his best friend's wives. I finally ask how he knows her and tells me they dated in the past. This all occurred yesterday and I'm still uneasy about it. I don't believe he did anything wrong; I more so can't get over how jealous (and other emotions) I feel.
