OK the guy that I liked use to text me all the time no matter what time of day. Everysince me and my boyfriend got together my friend texted him and told him that I love my boyfriend a lot more so now he never talks to me at all.The guy that really liked me has cancer and he's really scared but really not saying anything.I just can tell. I think that its a lot woser then what he's really telling everyone else.The problem is I still really care about this guy but since he don't really talk to me I feel like my feelings are going away. What should I do to get him to talk to me again?

Do you really need to be communicating with someone that you had feelings for in the past now that you have a new relationship?

If I may ask how old are you?
Your friend needs support but I'm sure he doesn't need any more stress from relationship issues. If you have feelings for this other boy and care about him, then why aren't you with him?

Yeah I think that his having cancer the last thing on his mind is getting tangled up with someone that has a boyfriend.
You aren't interested in the guy as a boyfriend and he knows your heart is with your boyfriend so he moved on and is doing what he needs to do.

The guy has enough problems, and doesn't need to see the girl he likes with a boyfriend, to try to act friendly, because he wants more, and your only concerned. Leave him alone, and let him get over you.

I agree here. He is probably pushing you away cause he has plenty to deal with at this point. I understand that you just want to be a friend and be there for him, but he has better things to focus on. Cancer is HARD, very hard. Surviving it is the hardest thing LOTS of people that I know have done. And dying from it is the most awful thing in the world. You see, he has a lot on his plate. If you really have something that you need to say to him, write him a card, and put it in his locker at school ((or anywhere he may find it)). Please only include well wishes though, nothing that will make him question his motives or make him sad. ONLY happy things right now.
