My friend has a crush on my boyfriend....please help me out...

I have this friend for almost couple of years and I have been going out with my boyfriend for 4 years. for about a month now I have had this feeling that she likes my boyfriend. she calls him sometimes asking for class notes(they have a class together at university) or asking him questions about the course. the question is that the more I think about her, the more I realized that I am right. when I told her that me and my boyfriend might get engaged in summer, she started saying all the stuff about how I should not get enggaged and that it is just too early. It really hurts to see and to think that your almost best friend has a crush on your boyfriend. my boyfriend loves me very much but I just don't know how to deal with her. please help me...

my neighbor,(shes 10) has this "thing" for my boyfriend 2. I just don't tell her when im going somewhere with him, or hes coming over to my house. Tell her straight up "I don't like the fact that you like my boyfriend, I still want to be friends with u, only if you stop liking MY boyfriend.

The question is that why it is a problem if anybody likes your b/f?
If somebody is nice people will like him/her, won't they?
If she does not want to take him from you you should be proud of that your older friend(s) like(s) your b/f. Anyway, you can ask your friend about her drift, or tell your b/f what you think.
