Once she is out of the house and she runs out of money, you won't be responsible to support her, will you? I wouldn't think so, but never know how different the laws may be from place to place.
I believe you will feel like a different person once she is out of there and you aren't be subjected to her personal business the way you are now. The less you know what is going on with her and OM, the better for you.
I sure hate that she didn't come to her senses b/c she's lost a good man in her life. When you start feeling like going out and meeting new people, you'll fine a wonderful person who will be just right for you. I truly believe that BJ.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
