Hi there -- Welcome to PC. I agree with what others have said --

1. The relationship is all about her; she's interested in you at her convenience.

2. You are an honest, sincere, and intelligent young man, who deserves better.

3. You don't owe her any explanations. She wants to be single; you agree. Whether you use your singleness to date or not date is none of her business. She's single, remember?

4. It may hurt like the dickens to end things with her, and it will be especially hard when you return to school. Get involved in other activities, so that you have no time for hanging out with her.

5. You are young, and dating experiences need not culminate in permanence at this stage of your life. You had fun, now it's over. Be glad for what you had and move on. Easier said than done, I know from bitter, painful experience. But your self-respect is at stake. You say you have low-esteem. Therefore, you must be sure to chose actions that contribute to a growing sense of self-respect.

Good luck, Confused. I hope you will keep us posted on how things work out for you over the long haul. I know someone who truly cares about someone as nice as you is out there.
