That person is thinking about spending Christmas with you. However, the situation where everything should prioritize you, not just on Christmas, seems to be burdensome for that person. The Strength card is telling you that patience is important. If that person starts to feel like "I'm the only one trying," they will gradually start to suffer. If you don't push yourself, restrain your selfishness, and show consideration for that person, they will likely try hard to make time for you, even if it means pushing themselves.
