Congratulations, you had a great couple-Christmas -- you struck gold with your gifts, the family dog liked you, and all relationship signals are Go! Go! Go!
How do you take this momentum and keep it going!
First -- love is a marathon, not a sprint. It's great that you've had such a spectacular holiday, but don't get disappointed if the intensity drops off a little. There is something about the season that can act like an "accelerant" that doesn't carry on with the same electricity after the holidays.
Second -- try to put a "name" to the things that went great. Was it your gift that said "think of me, because I'm always thinking of you?" Was it time with each others' families that revealed something new about each of you? Was it personal time when you reflected on the great year past and goals for 2011?
Actions: find a way in January to repeat the things you put a "name" to above -- what is another way you can tell him/her you think about them when they're not around. What other situations can you put the two of you in to continue to reveal more of each other? If you shared some 2011 goals, how can you take a big jump forward on them in January?
It's exhilarating to have a great holiday season with a growing romance, the secret to keeping the momentum is to draw on the same sources of success set to the new tempo of a non-holiday season.
