Need Christmas help......

I thought I'd never have to ask for help, but my wife of 6+ years, who I have 2 beautiful girls with, cheated on me. She also filled a false Domestic Violence order against me in October because I mentioned selling the house because she cheated, so I had to leave the house and not see my kids for 2 months while fighting it in court, I won, they dropped it. And was able to come back 2 weeks ago. She has put me through some hard times. I now have the kids and no help. I am trying to catch up on so many bills that she let go, as well as take care of my girls. It is Christmas, and we don't even have a tree... We went from being financially stable to falling behind. My wife is to busy with her new boyfriend and not wanting to help out. Christmas is right around the corner and I'm really hurting that my kids won't have much of a Christmas this year. I already lost my wife and had my family ripped apart, The last thing I want is for my kids to miss Christmas... Anyone who knows me, knows I HATE asking for help.. ..
