Virginia law on Spousal Support, if wife is abusive?

My wife is verbally abusive, does not like/want to do anything with me. Shows her a$$ if i try to just accept it and have my own life. Wont get a job, but shows her butt if i turn down any overtime (i work avg 50+ hrs a week). I pay her extra money each week so she can blow it on her family ( not much but its every week); She is always talking down to me, acting like a real Bit@h, and trys to act like her attitude is because of me. I try to take us on vacations and get aways, yet she refuses to leave the house, she just likes to stay at the house and clean and work in the yard (we have a small house 900+Squ-Ft). It could be a OCD issue, but o"well, she doesnt see a problem on her side. Ive helped raise her son from 5 to now he is 22yrs old. We have no children.

I think i want out, but honestly why??? I have to work 50+ hrs a week to support us, if i have to pay Spousal Support, then i will have to get another job also. im 40yrs old and she is 45yrs old. We live in virginia. I do better to commit suicide then leave and have to get another job also especially in this economy.. I feel like suicide most of the time now as their is no way out. Live in a misrible marriage or get out and and just live miserable...

Note: Her mom lives with us and pays nothing either. I was layed off for 7 months last year, and no one would get a job or assist, just trash talked me if i set on the couch at anytime during that time...

any suggestions?? (most of my posts are ignored, please answer this one).
