Is he using me as he gets with my friend?

I broke up with my ex on 27th Dec 2006. I still couldn’t let go till now. Today is the 2nd month of our break up. I am still so sad. Now he likes a girl in my class who is my friend. I know that my friend does like him. They talk to each other every night throughout the morning. my friend lied to me when I asked her why she didn’t come to school as we had planned. She never says the truth. Well, i knew she did that for my own good. Maybe she didn’t want to hurt me. But I can’t help feeling so sad. She is playing hard to get with my ex. She didn’t want to give him an exact answer. And now, I ignored my ex in school (btw, my ex is in my class). I promised him I would. Cause I know a girl wouldn’t feel safe if the guy she likes is always talking to his ex. I tried to help him as much as I can. Sometimes I just feel so stupid. It is like I am giving away the person i love to my friend. But I’d rather it to be in this manner; I’d rather see him being happy with another girl than to be with me and be sad. Whenever he is sad, I can just feel it. He said can just read him like a book. Of course I can. I’ve been through this stage before and we’d been together for 5 months. Our reason to break up is because of our religion and we’ve grew apart. When we just broke up, there is still a lot of love b/t us but…he just let go. Honestly, I tried my very best to save it but i failed and I failed very badly. Now, sometimes he will just talk to me about him and my friend. I know he didn’t mean to hurt me and stuff. I will just feel jealous and sad. But i will always be there to let him confide. I will always encourage him to follow his heart. Like yesterday.. my friend purposely wanted to make him jealous by changing her MSN nick to other guy name and changing her display pic to another guy, he was very very sad. And I console and I tell him not to worry. I told him many times that my friend does like him, just that she wont tell him now. Maybe you guys will ask me why do I know my friend likes him. It is my heart. Many things in life, we can’t just see it with our eyes, it is our heart. I see and I know. Girls, me too is a girl. Of course I know. It is obvious. After that around 1a.m, when my friend gtg in MSN, i knew they’re calling each other. therefore, I said bye to him too. And he just said bye. And off he goes. Am I being used? Am I? If i am, I am willing ya? Am I stupid? Can he feel that I am like his tool..whenever he has any problem, he can just confide to me? I love him with a love more than love. A love more than love… will he ever understand? Will he ever know?
