That was exactly what i did, grabbed her phone on two different days in front of the kids, tried leaving the house with it and she tried stopping me.
She's still having an affair right? I just don't think that under those circumstances you can detatch with her in the same house and all this going on under you and your kids nose.
I think the ROBx, Gucci approach is best, don't be an ass, just let her go. The only alternative is staying with her in an open marriage if that's what you want.
