I'm going to inform my fiance he did not get me a christmas gift last year
How could they forget, were you not expecting a gift that year?
Because it's a tradition to gift a gift for that special day
It is typical to give gifts to spouses on holidays. If you really want a gift you should remind them or help remind them about the holiday.
If I do that then he won't get the message and he won't buy one.
Your husband messed up and needs to be reminded. Don't be too harsh, just a gentle nudge in the right direction. I am sure they'll get the hint and remember to think of you next Christmas then.
