i dont know. probably not, there are other people who dont get jealous, and that is a good trait to have. toi care plus about other peoples happiness then your own, but be careful, toi deserve some happy moments as well.
No, I did much the same with my last crush. He really cared for this girl named Angie and they were so cute together but he was shy and was never going to admit to liking her.
I guess it was easy to do because I knew she made him happy and I loved seeing him smile. Plus I knew he didn't care at all for me and I knew that ultimately my feelings for him would get me nowhere.
