Wife neglecting family for church

My wife is born-again but her behaviour in the last few years is offending me. She rarely has time for the children and I as she’s always away on all weekends attending to this or the other church matter. She has church responsibilities literally every day. I have complained to the church leadership but received no response. She rarely sees the children, which has forced me to play the role of father and mother. We no longer make love since she is either on her periods, fasting or thinking about church matters. Is this okay or common with others? What would you do if you were in my place?
