Hey lovely, thought I'd chip in as a fellow Evangelical happy clappy Christian.
I really really do deplore churches who try and pursuade women to stay in relationships like yours. People mess up, and people can change but this man is showing no signs whatsoever of doing, and no commitment to the process. It's not like he's struggling to change, he's not even trying.
Are you aware of the Nooma videos by Rob Bell? There's a VERY specific bit about this in 'Luggage'..... Here's the link but Fast forward to about 9min30, it's only about 90 seconds worth.
It's basically saying that you can pray about it, forgive him and want the best outcome for him, but that does NOT mean you have to stick around to keep subjecting yourself to this same repeated hurt. "As a dog returns to its vomit so a fool returns to his folly"..... He's just going to keep going back doing the same behaviour again and again. You can forgive him if you feel that's the Christian things to do, but you don't have to let yourself continue to the subject of his awful behaviour.
I hope you'll find the video useful.
Oh, by the way, I was always taught that divorce in the Christian church is permissable for any of the 5 A's.
Abuse
Addiction
Adultery
Abandonment
Annulment
God doesn't like divorce. It's not part of his plan. But he knows we all mess up, some more than others, (in this knobheads case, some a LOT more than others) and he really wouldn't want you hurting. There's laws and teachings about divorce in the bible because....well....even though it's not nice, needs must and when things get well and truely shit and enough is enough then these things need to be sensibly dealt with. The church back in biblical times knew that too, hence then having guidance on how to deal with it. They don't want it to happen, but understand that it does.
God wouldn't want you reliving this same knobhead behaviour over and over and he wouldn't want your child being brought up in a house where they see this behaviour as an example of how a man treats his wife. He has made you strong, he's given you gumption and dignity and honour. He has given you the insight to set boundaries and expectations and your arse of a husband isn't respecting any of them. I firmly believe your church is wrong in asking you to just forgive him and stay with him regardless. They are doing you a disservice as Christian leaders. Tell them, and him, to shove it. Move on and let him get himself straight with God if he so wishes. You don't have to stick around to see that. Have a snot and tears cry, rely on your decent church family (I hope you have one!), get counselling from another church or professionals, let God hug you and rest in him, then shake the dust off your feet and start as you mean to go. The strong, capable and independent women he made you capable of being. Start your divorce and don't look back
