We used to be close, but I fell in love and she did not. She wanted to stay friends but it hurt me too much. I tried though, but she didn't like how things had become and told me to stop. I have continued to try but only get ignored, I regretfully said some rude things at her, feeling so hurt. I apologized but still havent heard from her. It's been a while now, and her birthday is coming up, I wanted to call and wish a happy birthday (after the day of course, I don't want to ruin her birthday or anything.) Is there anything else I should say? Or just leave it at a happy birthday, since I'm afraid she'll still want me to just leave her alone.
