So, yes, the house=X, but I think I can honestly say that I feel more anger that my work and effort in the house is automatically assumed by everyone--and I mean X, my family, my friends, you guys here--to be NOT worth the pain of fighting for or working through the pain of X. It seems to be the automatic thing that the LBS would leave the House of Pain.
I don't assume that the house isn't worth fighting for. I question your motive for fighting. I just want you to be honest with yourself as to the true reason you want to fight for the house. Especially considering that the L has advised you that it will be a battle you will likely lose.
As CityGirl pointed out recently on another thread, divorce is comprised of both an emotional break and a legal break. You cannot let the emotions control you respond to the legal/business aspects. Your pragmatic friend is correct: people will offer you emotional support but not financial support. You aren't a money grubber, you are making the best of a bad situation. I tend to look at it this way--he screwed you over once, are you going to let him do it again?
If you really want the house and are willing to fight for it even if means losing thousands of dollars then go for it. Just make sure you understand that it is a decision that will have financial ramifications for your future.
If you love somebody, set them free. http://tinyurl.com/2empx2g
