Just Another Day with More Stress...

I do not need stress. I was told this by my doctor. Even though I have said this, no one seems to understand this. My cousin insists on creating more and more drama! He breaks up with a girl to date MY BEST FRIEND, who, mind you, is nearly four and a half years younger than him. When she gets a boyfriend a reasonable year older than she is, he doesn't talk to her for a few months. He then dates a girl three and a half years younger than he is. After he breaks up with her, he goes back to girl one. A few weeks later, back to girl two, not my best friend, by the way. They broke up not more than a month ago, but then he went out with girl one again. He gets me involved because I hear both sides and cannot believe how stupid he is. Girl two is my friend as well, but she is sensitive. I hate seeing her hurt like this, but he just makes her hurt. My cousin is eighteen, my best friend is just  fourteen. Girl two is about fifteen as well. He needs to find a girl his own age and stick with her.
