"I'll always love you"

How do you tell someone who is in love with you that you are in love with someone else that you will never have?

All the little mind games that are being played on me, are the same games that I'm playing with him. And all it's doing is sending us in a circle. I was with him for two years and lived with him for a year, but my feelings changed and I wanted to break free. So I started to see him.

Well,since things didn't work out between us,"A" wants me back. But I don't want to get back in a relationship with him. Today he came by and said "I will always love you know matter what." And I know it's true because he has always been in love with me. The thing is that..I don't love him anymore.

We are only 18 years old and everyone thought we were married already. That is what kind of made me want to break away. I've even told him to just give me time and space for my feelings can settle because right now, they are so mixed up. He doesn't get the hint. He texts me "why don't you want to get with me?" And I tell him that I'm just not looking for a relationship. (Which is a lie).

I know how he feels. To want someone that doesn't want you back. And it sucks. But right now, there's nothing I can do and be honest with him.
