It's her day to have him, so I am going to respectfully decline her offer. Seems inappropriate for me to draw a hard line on the divorce agreement and then accept concessions from her....plus I made plans to celebrate with S tomorrow. But yeah, I sure wish I could see him today for my bday - but it's not going to happen.
First off...
Happy Birthday !!!!
Secondly...
Take advantage of that time, if she is willing to give it up.
It doesn't have to come with any obligations, other than it is your birthday....
Also doesn't mean that you have to change your mind about the other issue...
Put that guilt aside and do something un-expected today, and take advantage of her generosity.....she would....
