They are Christians I believe. I know I brought my ex into the church more when we were together and she stuck to it. And she married the new husband and he was a church member. At least that's my understanding.That's what I sensed.
So are your ex-wife and her husband Christians? If so, how serious are they about the Lord? If you want to talk about this but would be more comfortable in private, just send me a conversation.
My prayers are centered around my children for the most part and I do pray for their parents to have love for them and provide for their needs.
