I am so glad to hear of the progress you and W are making! Mexico for Christmas....that's wonderful!
My H is also trying in small ways. I guess some progress is better than no progress....right??? It's been four weeks for us (trying mode). And I can see progress. He is moving back home this weekend (12/17), I still cannot believe it!! (I'll post rest of story in new thread).
Remember time and patience. I keep reminding myself of it every day. And as long as you see the relationship moving forward, it's a positive sign.
Your Christmas get-a-way sounds like a great opportunity for the two of you to reconnect again. I hope you both have a wonderful time! Along with the sunscreen, pack those great DBing skills too!
