She never cared for me?

my clmate(girl) and me were good friends,we used to share almost everything including girls appeal.she even asked me"how would i look?".....i too stimulated her a couple of times verbally..tried to kiss her on neck..she never bothered...couple of weeks later she got to know that i love her by some means...i didn't propose her....month later she got married...she didn't invite me to her wedding..and when we were friends she never told me of her marriage proposal....what does all this mean....(girls help me in understanding this..i call this betrayal...can i?
