This was clearly an "It's you, it's not me" thing because in a nutshell, the friendship wasn't working for Alexis so she ended it. Jennifer said she would love to still have that relationship but she understands Alexis so it was ok, she was ok. I mean, if she had wanted Jennifer as a friend, she would have kept nourishing the friendship. Plain and simple. At one point Alexis mentioned that some people are "clingy." Which is why I never agree with the old, "It's not you, it's me" thing at any time.
So what makes a friendship any different? Is it different? Should you not worry about how you feel and think about what the friend needs? Or is that selfishness on the other's part by not recognizing that they may be causing the other to feel smothered?
