How can i get my wife to talk to me?

My wife hasn't talked ot me isince she left in Nov.she filed for divorce the first of Feb. I hav found out she is not seeing anybody else she still visits my Aunt and talks to her every day. She has said the reason she left was I was complaining to much and the lastmonth she was with me I was overboard with complaing and she couldn't take it anymore. I accused her of wanting to be with another man which pissed her off her ex used to do this everytime she was 10 seconds late getting home from work orr church. I miss read her actions I have never accused her of this before knowing how it affected her. and i had never had any reason to either. she had just withdrawn to such a point she wouldn't talk to me just put on her mp3 player and listen to Christian music and work on her silk flowers. she has siince said to my daughter that she cared abbout me but didn't want to come back to that and felt that if i had I would revert back to my old ways. can anybody help with some Godly advice?
