Wife left me with kids

My wife left me here in California and moved to Arizona with my kids after we got into an arguement about her brother moving in with us . He asked to stay with us for a few days while waiting for his pay-check to get his own place, and while doing so, he kept borrowing money from me for gas, when he got his check he dissapeared for a few days, then came back broke. when I brought my concerns to her attention, she threatened to move away with the kids if i kicked her brother out! a couple of days later, I got angry about that threat, more so because brother started missing days of work and complaining about his place of work. She was still adomant about mooving, i told her that if that was what she wanted to do to go ahead...not knowing she would move out of state. She moved out and left me with this guy! She's been gone for over a month now and she says she doesnt know if she wants to come back, still mad and hurt over everything and anything I have done to her over the 13years of our marriage. she is residing with her sister. A few days after she got to AZ she found out that her brother had temperarlily lived with her 23year old daughter and boyfrend (my step daughter) and done the same thing to them and he got kicked out. she then asked for me to kick him out since he was up to no good. I told her that i would do that , I would let her kick her own brother out since we are both on the lease of this home. He got his last paycheck and dissapeared without me having to ask him to leave and never payed me back the moneys that i owed him. My wife and I discussed reserving plane tickets for future date for them to return home, but flaked twice when the time came to do so. She says she needs time to deal with her hurt and pain that I have caused her over the years, she says she doesnt love me and hasnt for a wile. I am trying to apply the "No contact strategy" but it is hard, I am emotionally torn apart!!!! where do I go from here? I have a 3bedroom home on 2.5acres living by myself and struggling to pay the bills, we are self emplyed and she is my parter, it is getting overwhelming without her perticipation. Wheat should I do?
