I am already very accommodating. I've made schedule changes because her father could only come around Easter. I accepted to switch weeks in July because she's attending a wedding in OM's family in one of the most beautiful place on Earth and will then take the kids to the beach for the first time. This was one of our longstanding plans — even though she said at BD that we had no future plans. This holiday of theirs freaking breaks my heart: he will get to have her and MY kids with him at this joyous event. She will meet his friends and family. I had built this life, brick by brick, through sleepless nights, career sacrifices, forgiving an A, love and understanding. Yet, she takes it away and gives it to someone new, overnight. Also, in 2008, when D6 was 5 months old, we went to a wedding near that region and it was an important moment in our lives, something I look back to as a reason why we had a beautiful M. We have beautiful family pictures from that. Now, she's living it with someone else, telling me "I can't look back, only forward." EFF YOU SEE KEY! And I've said NOTHING of my pain to her, just "Sure, we can rearrange the schedule. I'm sure the kids will love the beach."
Well - I'm just going to throw this out here - the reason I mentioned potentially accommodating her on future birthdays is not for her - it is in fact for the kids. She might have a point that the kids might like to see both of their parents on their birthday. And I say that even though my own D6 has a birthday in a couple weeks and there are certainly no plans to spend any time all together that day. When the dust settles, I might be more open to it. Saying that you will consider it, or for that matter actually considering it in the future, costs nothing.
