Great answer, OronD. Thumb up!
Tanya, your fiance does not hear what you have to say because he does not care to listen.
He is your fiance in name only; nothing more. His actions do not back it up, nor do his words.
In fact, after seeing what you wrote about his behavior I have to ask: Whose idea was it to become engaged, yours or his?
I am not trying to be mean, but it sounds to me as though he may have agreed to an engagement just as a means to silence your talk about marriage. And if so, then it is no wonder he does not behave in the manner of an engaged man - because he never wanted to be one, so he doesn't think of himself in that way.
Think about it. Could that be it?
