Coming back to Jesus Christ

So i was raised in a Christian house hold was saved at the age of 12. I lived right for god for a few years then began to backslide. I've lived in sin for 15 years. In that time i met my wife and we got married and have a beautiful daughter and one on the way. Recently God through the holy spirit had delt with my heart and i knew i had to come back to Jesus and live right for God and thats what i did. Now im a believer but my wife isn't, its an uphill battle for me everyday. I pray like 20 times a day and read my bible constantly. She gets mad at me and says i wish you'd put as much love and effort into your marriage as you do that book. I try to witness and not be condemning or judgemental but everything i say just comes out wrong. To be honest i dont know why im saying all this i guess im trying to find help and comfort from fellow Christians and seek out God's word. Thanks for listening
