I'm torn between two people for my wedding party. It is important to have three people to my fiance. I already have two, but the 3rd is tricky. I have a friend of 6 years who was my boss when I first met her, then we became friends (we are the same age). She has been there for me through break ups and happy times. She has also written me letters of rec for jobs, etc. but the problem is she can be flakey. She cancels on dinner plans about 40% of the time and is often late. But she does make it almost every week for our tv show, although she is usually 5-20 mins late. I love her but am worried she isn't reliable. The other option is my cousin. We are friends, but not as close as my friend above. I used to be best friends with her older sister (long story but she moved in with her bf and the rest of the world disappeared), so I'm afraid asking her might cause family drama. I could just ask both but our wedding is small so we'd prefer to just have one. Who is the better choice? Thanks!
