If your relationship can't withstand a little obstacles, your gf probably don't love you as much as you think, regardless of how long the duration of relationship is.

I guess silent treatment shows how mature you are, instead of communicating like an adult on what your bf did that bother you, you choose to act immaturely so that your bf can play guessing game with you.

That shows how much you really cared about your bf.

Look, if she doesn't have the decency to give you a closure, what makes you think she really value the relationship?

You think a person that loves and respects you would do this to you?
