Dear Erica,
I am sorry to hear that you are going through this.
All I can say is that YOU have to take care of YOU because noone else will. The guy that you are seeing seems incapable at the moment of even taking care of himself and that is not your job . Also after just over two months you seem so very unhappy, envision what it will be like in another two months or more down the line ? Do you want to keep feeling like you do ? What does ERICA want and What does ERICA deserve ? Will YOU be happy continuing the relationship ?
