Sorry to hear your situation.

Assume you are a non Muslim.

You can divorce either by :-
Mutual consent
Prove physical and mental abuse
Stay apart from each other for 2 years ( must be proven that you two are not functioning as a family unit ). Once proven, the marriage is null. This process still must go through lawyer and such.

Alimony and such, all I can say is good luck trying to get that from him.

As for the house, Both of you have to agree to sell, then can sell anytime. If one party resist, then need to divorce then get lawyer to split the house. This also can get into issues in terms of value and such. Example, if he is paying all the while its unfair if you ask half the value. Again, its all a matter of tolerance and acceptance.
