I think more that the on/off switch is.... thinking that this may be going south any day now, instead of, is this for real? We always get our hopes up that "maybe this time" but then south we go. I'm there now. even though I'm not with my AH he is building a realtionship with the kids and it is going well, but in the back of my head is"when is this going south?"
Hang in there!
