For the last 4 years, I've been on my own with DD (now 11). I've always says my ex can have her as much as he wants. Until December last year, he took eow and a couple of weeks in the holidays. Now this has changed and my ex has no weekend contact, and takes her for most of the holidays.
That means I've just had 6 weeks of full time with DD, and I'm 2 days into her being with Dad for 10 days.
Now that I've had some breathing space, I'm feeling like my right arm has been cut off. Have never missed my DD as much as I do now. I think being full on for 6 weeks without a break has made it much harder to be without her. Do you have a contact pattern like this? Does it feel odd when DC aren't there?
