Zephyr, you are doing amazingly well for your situation. As you mentioned on my thread, having our spouses still in the house is a blessing and a curse.
A blessing because we have the time to work on ourselves and a curse because it is rather difficult detach. I have just started thinking about codependency and my R with my H. All we can do is keep plugging on and be thankful for the good stuff in our life.
There was someone on here...can't remember who it was, but had a grateful journal for every day. I've done it a couple of times when I was struggling more than normal. It had to be very specific items, ie I made my H laugh today, or saw a deer on my way home, rather than my house, my kid and so on. It always seems to help me. Maybe you might want to try it? It just puts things in a different perspective when I am frustrated or lonely, or sad.
