I think the "I love you but won't share you" thing was perfect. Its true, and its the right thing to do. And Mark is right, sex for a woman (no matter what we say ;\) ) is emotional.

Things are still going well, I think your W is stressed about work and kids. You aren't putting pressure on her, so just wait for her to 'level out' and things will be fine.

PS: I hate LimboLand too!
