Ok...hold da phone here. You want to take your kids with you when you go our for your anniversary? BZZZZZZZZ!!!!
There are PLENTY of other opportunities to take the kids with you when you go out. You two are trying to re-build YOUR R, don't take the kids on an important occassion like this, that's just using them as buffer.
I know you may not feel like "celebrating" that you've made it 11yrs, but use this as a "date night" if nothing else. Don't downplay the occassion by making it a "family night".
I don't mean to sound like I'm against kids...I'm not, but my H have made the mistake of including our S in almost everything we do...we just don't make the effort for a sitter (when he loves them). You including the kids on your anniversary kind of rang about the same as mentioning giving her back the ring....this of all nights is about the two of you!
Re-make that nice dinner reservation, just in case she comes back with an "I don't know...whatever you wanna do." Sorry about the cyber-smack upside the head here, but I feel you were about to reel off-course
