Pity guy,mostly u have to shar

property, fortunately you're in MD, a very expensive house area but also if you hire a very good lawyer, maybe you can get more share from divide ur house. It's said divided marital property by equity(Fair), it depends both party's income. U need to contact an attorney to ask the detail.
Why don't you try to find a lover for her? Then she's happy and you'd be happy, too!(have ur house alone), I might be happy to help if you want, hehe.
