Really really really long story short... Kidlet, Dog and I have moved back in with my mother for the time being. It got to the point where I felt we needed to live separately to work out our problems. It's nothing so bad that absolutely cannot be fixed, but we're way past the place where we can work it out without non-biased third-party input. So we're working on finding affordable counseling, but we're looking at probably 6-12 months of work, which means that we likely won't be living together when the baby arrives in April.
It sucks. And it hurts. And I don't think I have cried so much in a very, very long time. And that's about all I want to say about it.
