Yes, this is going to be horrible for the kids. Sadly, not because they will be seeing him less, but because they will be seeing me so much less. I have been a stay at home mom with them for the last 6 years (ages 6 & 3) and he wants 1 week on and 1 week off for custody. We are going to work it out that I will see them during the week when I pick them up from school and keep them until he gets home from work, but it will be a HUGE change for them not to have their mommy around. And yes, he has said some such crap like "the kids will be happy that their dad is finally happy." B.S.
One thing my divorce atty suggested is to start the one week on, one week off while we are still living together. That if he won't move out we can start with the arrangement and see if that wakes him up at all. That getting the kids ready every day and feeding them breakfast and packing lunches and feeding them dinner after a long day at work, etc. etc. isn't all it's cracked up to be. Anybody try that before?
In the meantime, I'm going to continue what I've been doing for the past two days, working on building some intimacy between us with open discussions etc. See what happens. We have two concerts we are going to this week, which is something we use to do together all the time and is definitely something we share that he does not with the OW (she has very different musical tastes and music is really important to my H).
At the end of the weekend if things don't seem to have changed at all I might suggest the week on/week off schedule and start making myself really scarce on my week off and make sure he does the same on his week off. He can't miss what he has around him all the time, right?
Oh, and the OW's H is trying to repair the marriage. Sometimes he thinks he is making progress, but he isn't sure.
