Sorry to hear the tough times you have been through. Some of it does sound familiar though.

W has been diagnosed with bipolar type 2 disorder. She is and has been in treatment, but it does cause issues. Like you mentioned:

Our main problem has been her mental disorders, and if we had addressed those I think all our other problems would have been workable before they escalated to where they did.

While she has actively sought treatment, I probably should have been more involved in trying to understand why her behavior changed often and what I could do (or not do) to help her and me through the tough times.

If I would have found DB sooner, I might not be in this sitch!

W is defintely pregnant, only 2-3 months along, but there is no doubt.
