Think everyone is different, regardless of nationality. From experience just coming out of a 4 year relationship, my girlfriend didn't express her feelings about things. Reason for breakup was silly but she said it was "the last time she was going to get hurt by something I said". After talking about there were several times things were said by both in the past that "hurt" her feelings. I said that maybe if she had expressed her feelings at those times it wouldn't have ended up like it did. The classic men are not mind readers came up. If I was ever "hurt" by something she said or did, I let her know so she would think in the future.
