1. Seek a counsellor today, and get your wife involved in the process.
2. Make a list of your responsibilities and be a slave to it, if that's your big downfall
3. Most importantly, pray with your wife about your marriage. It will bind your hearts together in your effort to improve your marriage, and let God work in a bigger way. You said you cannot seem to do it...You can do all things through Christ. It's a promise.
