This women fully deserves a parping!
I feel incredably sorry for her if her feelings towards her hubby haven't changed in the slightest. I know that what I feel for both Dd and Dh go far beyond love, but it's a different feeling for each, as it should be. Since Dd's arrival the relasionship is closer than it's ever been, both having seen a different side to the other in our interactions with Dd that have amazed us. With these revelations our relasionship has grown and matured in ways that I never believed it could. It doesn't mean that we've been (in my sisters vocab) "getting it on".
If she feels that the measure of her love towards her husband is by how much she gets it, she is unaware of the meaning of love.
As for how she loves her hubby more than her children, doesn't she understand that her children need her. Her hubby is her partner, her children are dependants who rely on their parents for everything. - Maybe she should look up what that means and why women (and men) put their children beyond everything - even their partners.
Will stop ranting now - sorry.
