Pray for my family in this chaos

Ive know my wife for 10 yrs but we have been married for five. in that time we had kids bought a house and racked up allot of expenses.i believe every time she has asked me to make a change in my life i have weather it was quite a job and get another one, get rid of my credit cards, cut off friends she believed were bad for me. when it came to the kids i was very amenable. i took care of them allot while she went and hung with her bff and went to church. she even went to a couple church conventions for a couple days at a clip and i stayed home with them. i was a good husband and father. At about a year and a half ago before our wedding anniversary she started acting weird. always on the phone staying down stairs while i was upstairs and then saying she fell asleep watching TV which in reality per the phone records she was talking to the guy from work. then all of a sudden she said she wanted a divorce. i asked her to lets work on the marriage which after a couple days she agreed to. then the day after my birthday after we went out to eat and she made me feel everything was good she woke me up the next day and said she wanted a divorce. again me not really going for it asked her to lets do counseling and that since Ive always done what she asked maybe she can do something i ask. so after about two weeks she back burner the divorce talk but she was texting and calling the guy at work that she secretly was involved with and having dinner and lunches with on a regular. he knew all about me and knew all about my marriage. when i caught wind that this was going on the entire time she wanted to leave which added up i asked her to stop talking to him and to work on her marriage. she said that her friends and her job and even this guy means more to her and she loved them more than me. since then she has alienated me away from my kids by starting arguments around them which turn into loud arguments which i look like the bad guy. last week she ask me to leave the house and when i said no because i had no place to go she filed false charges against me saying i assaulted her and had me removed from my house and made it so i cant see my kids. which the judge over turned me being able to see my kids but told me i can not return to my house. i have never done anything to my wife but love her put a roof over her head and follow her request, im currently living out of a motel and have no money. i love my kids and love my wife thru all of this but im not sure where to go from here. My wife use to be a strong child of God now i don't know whats going on. just pray for my situation as i pray for it.
