26 and all alone

I love him. He says I'm his best friend. I've known him two years. We did everything together. I moved out of state and within 4 months he has a girlfriend. I wish I was her. I never made a mood because he said he wanted to become a monk, and I respected that and wanted him to be happy. Now he's with her...and I'm alone. I've cried myself to sleep every day this week thinking about him. I miss him so much. I love him so much. I know he's just another whim for her...all the guys she dates are...she's going to break his heart and he'll want me to make it better. I've held him as he's cried before, but no one's ever been there for me in that situation. I wish he could be. But instead he's going to stay with her until she dumps him for the next new thing. He deserves better. I deserve a chance. I'll never get it. I'm too old. I've never dated. Never had a BF. I quit...
